Min: Can't minimize window in some linux distros

[lee-yunseok]

As a sub, I found a problem in video streaming. Min can't minimize window when streaming video on youtube and vimeo. It probably the same on other streaming platforms.

I'm not sure if this problem that only occurs in RPi.

Is the video in fullscreen? Is the issue that there isn't a minimize button, or that clicking on it doesn't work? Do the other window buttons (close, maximize) still work?

[lee-yunseok]

Other buttons work fine.

I thought it only occured in streaming video before but the minimize button doesn't work anymore.
More exactly, when I click the minimize button, it work but restored immediately.

Added: Minimize work when there is no any tab.

I will check again after completely reboot pi.

[lee-yunseok]

Still having the issue. Perhaps this problem only seems to happen with RPi?

[PalmerAL]

I can't reproduce on Ubuntu, so it may be specific to RPI-OS. I have a Pi I could test this on, but it may be a while before I get around to setting it up again.

Does it work if you enable the "use separate titlebar" option? Also, was this working in a previous version?

[lee-yunseok]

Yes it work with enable separate titlebar. I don't remember when this feature was added but minimize worked before.

[lee-yunseok]

Re-install also doesn't work. So enable separate titlebar may be needed for pi users.

I have same issue on Arch Linux KDE

Min 1.15.0

Hi! The same on Lubuntu 18.04.4 64 bitafter the latest ugrade.

[Sestowner]

I'm facing the same issue when I disable the "Use separate title bar" option.
OS: Linux Mint 19.3
Min: 1.15.0

Looks like this issue derived from 38c9ff4ac4adf3db18b213b30a4ad8f3fdf502b5.

I think this is also related to this...

if browser is maximized, pressing CTRL + R twice to reload browser i get few pixel margins at the top of the browser. Remaximizing the window fixes this

[PalmerAL]

@Sestowner Thanks for finding that. I don't see right now how that could cause this problem, but I guess we can back it out if we don't find a solution.

I've tried this in:

• Stock Ubuntu
• Ubuntu with vanilla GNOME
• Ubuntu running LXQt

and I can't reproduce it in any of them, so there must be some other factor. Are there any other factors that you can think of in your environment that could cause this?

@shalva97 That's an unrelated issue; the drag space gets hidden when you maximize the window, but it loses the state when reloaded.

[Sestowner]

I just checked this on Cinnamon (before I used Openbox), and I didn't encounter this issue.

[PalmerAL]

I was able to reproduce this once on Openbox, but after restarting Min, I no longer see it.

[Sestowner]

BTW, I can minimize Min on Openbox when the address bar is active or when the task overlay opened.

[PalmerAL]

Thanks, I can reproduce it now. (And that would make sense, because webviews.placeholderRequests.length === 0 will be false in those cases).

[PalmerAL]

This is strange:

• If you have a button inside a frameless window that calls minimize when clicked, then it actually triggers a focus event on the window as it minimizes.
  
  
  
  • If you make the window not frameless (which is what "use separate titlebar" does), it doesn't happen.
  
  
  • If you get rid of the button (and call minimize() from setTimeout), it doesn't happen.
  
  
• Due to the change above, when the focus event happens on the window, the BrowserView will be focused (which is what should happen, in theory).
• Focusing the BrowserView un-minimizes the window (which also doesn't make much sense).

The only thing I can think of at the moment is whenever we get a focus event, to check if we called minimize shortly before that, and ignore the focus event if we did. But that seems like it's not a very good solution.

[PalmerAL]

@Sestowner I've added a workaround for this in 99d94d06874253da1ff66bfe79f00ad2727b103d; can you test it and make sure that the window now minimizes correctly, and that the page still gets focused again when you re-focus the window?

[Sestowner]

@PalmerAL I tested your workaround and it works great for me.

[PalmerAL]

@Sestowner Thanks!

I'm going to close this since I think it's fixed, but if anyone else still has this issue after the next update, please let me know.
