Sway: Wayland compositor does not work with Firefox

[stransky]

Hello,

I work on Firefox Wayland port and I'm having an issues with Wayland Firefox on Sway compositor. Mouse cursor is not shown, popup menus are not shown and the browser does not response to uset input.

KDE/Kwim (https://bugs.kde.org/show_bug.cgi?id=397834) have similar problems. It can be caused by wl_subsurface which is attached as an overlay of wl_surface owned by main Firefox toplevel GtkWindow.

You can check Firefox on Wayland by 3 ways:

1) to run Firefox Wayland from flatpak (https://firefox-flatpak.mojefedora.cz/)
2) to build Firefox by itself with:
ac_add_options --enable-default-toolkit=cairo-gtk3-wayland
and run as GDK_BACKEND=wayland ./firefox
3) you can also install Fedora 29 where is firefox-wayland package available.

Please let me know if I can help.

Same thing happens for me on rawhide. However the version is still 0.15.2. I will try 1.0.0 beta when I have time. Everything seems to work in gnome and weston.

Hi, thanks for reaching out!

You might want to first try in rootston (wlroots' reference compositor). I just tried the latest Flatpak nightly and it works there (!). There are performance issues though. I also noticed you create a lot of wl_keyboard instances, this may be related.

I'll try to see why it doesn't work in sway master.

I can reproduce problems on fedora 29 with firefox 63 and sway 1.0.0 beta 1. It's way closer than it was last time I checked. It actually runs and you can kind of use it. But scrolling is choppy and certain context menus will crash it.

To crash it: Launch firefox-wayland or GDK_BACKEND=wayland firefox, then click into the address bar and start typing. The autocomplete suggestions will populate which will trigger a crash with this output:

Gdk-Message: 22:45:14.620: Error reading events from display: Invalid argument

I can reproduce problems on fedora 29 with firefox 63 and sway 1.0.0 beta 1.

The address bar crash has been fixed in Firefox 65.

Just curious (maybe not releated) but there are still bugs on mixed dpi multimonitor setup?
When I clicked menu in Firefox it was opening on another screen and I had other similar glitches.

This sounds like a Xwayland-related bug (which has been fixed). We're talking about the Wayland version here.

[HoshiYamazaki]

I think I used wayland version, but I'm not sure. And it was not only me, there are other people who have bugs on mixed dpi multimonitor setup:
https://bugzilla.mozilla.org/show_bug.cgi?id=635134
(Latest updates).
I don't have now Linux machine to check it if it persist, sorry. Was just curious.

The same with sway 1.0 beta...

But scrolling is choppy

...similar thing reported at b.m.o:

https://bugzilla.mozilla.org/show_bug.cgi?id=1493493

I will try 1.0.0 beta when I have time.

Firefox-nightly 65.0a1 does not even launch for me with GDK_BACKEND=wayland

Firefox nightly 65.0a1 still has the browser bar crash. It seems to perform in an identical fashion to firefox 63, including the same error message output and performance issues.

[baloo]

I tried the hg master of firefox, wlroots and sway. And I'm observing the same behavior as @JonnyMako. But I also tried to start firefox in weston, and it appears to be starting to be okay.
I also see the IPDL protocol error errors, on both sway and weston.

I'm not quite sure how to debug this issue. Any help to debug this further would be appreciated here.

[uwqwxing886]

@JonnyMako I was seeing the same Gdk-Message: Error reading events from display: Invalid argument error message that you posted in https://github.com/swaywm/sway/issues/3115#issuecomment-439584937. Try clearing the clipboard before launching firefox. See #3170.

[emersion]

@stransky: just merged a patch that prevents Firefox crashes in wlroots. Now I'm able to run it as long as I don't copy something (the patch for this second crash is pending). However…

I work on Firefox Wayland port and I'm having an issues with Wayland Firefox on Sway compositor. Mouse cursor is not shown, popup menus are not shown and the browser does not response to uset input.

I'm unable to reproduce this. Can you make sure you're running the latest sway and wlroots commits?

Note that even if it _works_, it's very slow. That might be due to the fact Firefox creates ~50 wl_keyboard objects pretty quickly. Not sure why it happens on Sway and not on Weston.

(In both Sway and Weston, Firefox uses wl_shm)

[J0nnyMak0]

Note that even if it works, it's very slow.

Further note that it gets slower with every key stroke, until it just freezes. Additionally, for non-us keyboard layouts, modifier keys don't work. (I filed a bug about this on mozilla).

Can you please provide a firefox backtrace where the wl_keyboard objects are created? I'm not aware of that at Firefox code. Thanks.

[stransky]

I see only this place - so is the wl_seat send multiple times?

[stransky]

Thanks, it should be handled by https://bugzilla.mozilla.org/show_bug.cgi?id=1507475

[martinetd]

phabricator link of the same: https://phabricator.services.mozilla.com/D12255 (more direct for people like me)

Haven't looked at the code in details but yes I believe this should help; not listing all global registries everytime you need something is the way to go! :)
I'm too lazy to rebuild firefox, but someone here ought to be able to confirm sooner or later

[johnp]

I downloaded a build with the patch for bug 1507475 from autoland (direct link linux x64 pgo) and can confirm that Firefox runs far more smoothly now on latest sway-git/wlroots-git.

edit: modifier keys also work smoothly now and don't get lost under load as before.
edit2: fix is in Nightly since build 20181123220228

[uwqwxing886]

Firefox is not just usable but fast and stable using the build in https://github.com/swaywm/sway/issues/3115#issuecomment-441247363 (previous comment) and the wlroots fix in https://github.com/swaywm/wlroots/pull/1384.

[stransky]

Thanks for the confirmation, I'll backport the wl_keyboard part of the patch to Fedora Firefox package.

[J0nnyMak0]

Great! Firefox with wayland backend is working well enough for me to switch to using it by default! A couple of minor issues:

1. Menus get stuck on screen. So when I enable any menu, lets say the right-click context menu, and then click outside to disable it, I can't get rid of it. It is still drawn on screen.
2. Firefox with wayland backend does not pick up GTK themes.

[emersion]

Menus get stuck on screen. So when I enable any menu, lets say the right-click context menu, and then click outside to disable it, I can't get rid of it. It is still drawn on screen.

Does scrolling the page underneath the menu fix it?

[J0nnyMak0]

Does scrolling the page underneath the menu fix it?

Yes, scrolling gets rid of the context menu. The issue is not limited to context menus though. The menus in the menu bar are drawn over each other. So if I select File menu followed by Edit menu, then Edit menu is drawn over the still seemingly open File menu. All menus are reset when cursor is moved over the webpage area.

[emersion]

This one is likely a sway bug. Can you open a separate issue about it?

[J0nnyMak0]

This one is likely a sway bug. Can you open a separate issue about it?

Will do.

Also, in newer firefox-nightly wayland, selecting and copying any text from webpage crashes firefox. I still run into the problem with firefox not starting up if clipboard has content. I suspect these are related.

[emersion]

You need to use swaywm/wlroots#1384.

[J0nnyMak0]

You need to use swaywm/wlroots#1384.

Gotcha. Thanks.

[stransky]

Will do.

Also, in newer firefox-nightly wayland, selecting and copying any text from webpage crashes firefox. I still run into the problem with firefox not starting up if clipboard has content. I suspect these are related.

Can you please provide a backtrace of the crash? I'd like to fix that. Thanks.

[emersion]

Can you please provide a backtrace of the crash? I'd like to fix that. Thanks.

Don't worry about it, it's a sway bug that has been fixed.

[wernerb]

@stransky

It is very stable now, haven't had a crash since the above fixes. There are still problems:

• Context menu's, rightclick menus, also extension windows (1password etc) * are misaligned and not following Y position of sway*

Can be repoduced with: you'l see that rightclick's / menu's will be offset.

output eDP-1 {
 position 0 80
}  

See

• Sometimes creating a firefox window will result in it crossing its sway window boundary and I have to fullscreen toggle to return it to correct dimensions
• Moving a window from non hidpi to hidpi often results in zoomed in window. Again, fullscreen toggling fixes this.

[ammgws]

Context menu's, rightclick menus, also extension windows (1password etc) do not show up at all.

I haven't experienced this, but just testing now the right-click menu sometimes disappears when the cursor moves off of it. It does reappear element-by-element when I move the cursor back.

[wernerb]

@ammgws see my edited post. it has something to do with positions or scaling. Could you try to reproduce by following my config above?

[ammgws]

Slightly different setup but anyway I had no issues with it scaled (apart from the same disappearing behaviour mentioned above)

Don't have time to test any further atm.

[wernerb]

Weirdly enough it seems to be the vertical position. horizontal position is fine so try to set your monitors to

output $monitor1 pos 0,1400 res 1920x1080 scale 2

I seem to be able to reliably reproduce disappearing right-click context menu by right-clicking and very quickly moving the cursor onto the menu itself. This maneuver has to be quite quick and easier to do with a mouse. When I do this, I don't see part of the menu and the items appear as I move the cursor over them. @emersion let me know if you want a separate issue for this.

I've managed to build firefox-63.0.3 with wayland support on my gentoo system using patches from fedora package. It's very stable and smooth, but I've ecountered two minor problems. Don't know if it's problems with my build or real bugs.

1. Sometimes firefox doesn't start right up. It starts two firefox processes, one main process and one tab process and nothing happens then, no window shows up. It outputs in terminal only this:

Attempting load of libEGL.so
IPDL protocol Error: Received an invalid file descriptor

I have to kill these processes and try to start it again. After some try it starts normally and works well.

1. Clipboard works weird. At first it looks like bug https://bugzilla.mozilla.org/show_bug.cgi?id=1504689 - copied text is not being pasted in another applications (but I've got patch for 1504689 applied). And then, after I switched back to firefox, and after some time switched back to that application I tried to paste to, I see the text was pasted. But it took some time. Why could that happen?

After changing the vertical position I could no longer get right click menus or other menus to show (probably being rendered off screen I guess?)

I can reproduce this. It seems that disabling OpenGL "fixes" it (GDK_DEBUG=nogl).

Weirdly enough it seems to be the vertical position.

This is a sway bug. @wernerb Can you open an issue?

[wernerb]

@emersion done in #3233

[J0nnyMak0]

Also auto updating nightly sometimes crashes Sway.

[emersion]

crashes Sway

Please submit stack traces (coredumpctl gdb sway then bt full) in a new issue.

[emersion]

Thanks, looks like it.

FWIW, non-trivial Wayland clients should always use eglSwapInterval(0). There's no valid reason to ever use something else.

[emersion]

@stransky Another thing our users reported is that sometimes menus are off-screen and/or hidden. This happens because you use subsurfaces instead of xdg-popups. Subsurfaces spanning outside of the window geometry have no guarantee to be visible, whereas xdg-popups will be more cleverly displayed by the compositor.

I'm seeing lots of crashes in nightly builds starting yesterday. Just opening a new tab and typing into url field seems to crash firefox, for example. Anyone else seeing frequent crashes?

[johnae]

Yes. Since yesterday I believe.

Is the Flatpak fixed? I just installed it and it still has this issue. Running on Kubuntu 18.10.

[stransky]

You don't need that flatpak any more to test wayland builds.
Just run an official Firefox nightly as GDK_BACKEND=wayland ./firefox i.e. you need to set GDK_BACKEND env to wayland.

[wernerb]

@stransky still having issue #3233 with latest nightly. Its been pointed out that its due to using a deprecated method in firefox? Is this fixable? Like I said before no context dialogs are possible with any sort of vertical output set.

I think it's https://bugzilla.mozilla.org/show_bug.cgi?id=1423598

[ojab]

I have an issue with Alt+[1-9] not switching tabs (and just typing [1-9]) using latest Nightly + sway from git master.
It looks like https://bugzilla.mozilla.org/show_bug.cgi?id=1509152, but it's fixed according to https://github.com/swaywm/sway/issues/3115#issuecomment-441247363.
Can anyone else reproduce it?

[trobjo]

@ojab I have this issue as well, and it's not just tab switching but the Alt key behaviour at large. I can't even Alt+Left/Right arrow to navigate pages.

[ojab]

Filled https://bugzilla.mozilla.org/show_bug.cgi?id=1519940

[cg9999]

@stransky new bug filled here #3506 since this only seems to happen under sway. Not sure if firefox or sway is to blame though.

[tallandtree]

I've got a similar issues today with Firefox on fedora 29 with the latest patches of both: it crashes frequently and gives other browser issues. But Chrome crashed as well just now, so not sure what to think of it...

[eternal-sorrow]

The problems I see with Firefox 65 (running as native wayland application) in sway-1.0-rc1:

1. I'm still having problems with copying text from Firefox to another application as I pointed out in https://github.com/swaywm/sway/issues/3115#issuecomment-443467939. After some experiments I found out that it only happens when the other application is on a different workspace than Firefox. I have to press paste keybinding, then switch back to workspace where the Firefox window is and then back to my application to get text pasted. And even this trick does not work with Telegram flatpak app (and maybe other Qt and/of flatpak apps, I don't know about it). I can't get text pasted in Telegram unless I move Firefox and Telegram windows on the same workspace.
2. When I open a link from another application, it really starts loading in Firefox only when I switch back to Firefox window. Turns out it only happens when that another application is on another workspace than Firefox window, so it may be related to the first of my issues.
3. Some issues with resizing Firefox window in some circumstances. For example when there is another tiled window alongside the Firefox window and then it becomes a fullscreen window, and then I close it while it's still fullscreen. Then Firefox window sometimes stays tiled to the side of the screen while there is an empty space on the other side.

[progandy]

@eternal-sorrow Your 1. and 2. have probably the same cause as #3561, firefox blocking while it isn't rendered on screen. Telegram might have the same problem.

[smlx]

@eternal-sorrow is 3 similar to #3055?

[eternal-sorrow]

It kind of is, as far as I can see, referenced issue happens after firefox startup, also it's probably related to firefox on Xwayland. My problem happens only with native firefox wayland application. Also it happens in very strange circumstances (I still can't reliably reproduce it).

[firat]

I have an issue with Alt+[1-9] not switching tabs (and just typing [1-9]) using latest Nightly + sway from git master.
It looks like https://bugzilla.mozilla.org/show_bug.cgi?id=1509152, but it's fixed according to #3115 (comment).
Can anyone else reproduce it?

Happening to me too with Fedora 29, Sway & wlroots master and Firefox 66 Beta.

[meMuszr]

@trobjo @firat with GDK_BACKEND set to wayland and running firefox, switching tty's (1 -> 2 -> 1) will temporarily fix the alt + [1,9] tab navigation.

[Depau]

I'm currently using Firefox Nightly and it seems all issues have been fixed

[ddevault]

Any remaining issues are probably firefox problems.
