Issue description

Since a recent update, zoom-us shows a blank UI.

Steps to reproduce

Install zoom-us and launch it. Settings and other windows can be activated via the tray icon, but they are all blank.

Might be - I think I'll just leave the proof as an exercise to possible other interested readers ;-)

/nix/store/s29764w9j9s6x3jjf0q7mp0ya85iwz84-zoom-us-2.4.129780.0915/bin/zoom-us works for me

  • system: "x86_64-linux"
  • host os: Linux 4.16.10, NixOS, 18.09.pre.0832208 (Jellyfish)
  • multi-user?: yes

@tadfisher can you check if it works from commit 969a39bd09003d8fbc5d15d18472c60ee2058aec and commit before that?

I don't even get a blank screen: https://github.com/NixOS/nixpkgs/issues/47622.

Can someone please share a script (like I did in #47622) that makes any fairly recently version of zoom run?

@coretemp that script isn't very good. What you want probably is the following:

  • clone nixos/nixpkgs-channels the branch you like most
  • cd there
  • run ./pkgs/applications/networking/instant-messengers/zoom-us/update.sh. This will update zoom source version
  • then run nix-env -if . -A zoom-us to build and install it

Maybe you can try and wrap that into script?

@danbst Thanks a lot for your response. Why would the script not be "very good"?

The version below assumes a bit more (the non-free configuration bit), for example. So, if someone can still fix that, then the below would work on all systems.

I wrote the following (and that gives me a working Zoom):

#!/bin/sh

version=18.09

src=$HOME/src
name=nixpkgs-channels-zoom
zoom=$src/$name
mkdir -p "$src" &&
cd "$src" &&

if [ ! -e "$zoom" ]; then
  git clone https://github.com/NixOS/nixpkgs-channels.git "$name" 
else
  (cd "$zoom" && git pull)
fi &&
cd "$zoom" &&
git checkout nixos-"$version" &&
./pkgs/applications/networking/instant-messengers/zoom-us/update.sh &&
nix-env -if . -A zoom-us &&
"${HOME}"/.nix-profile/bin/zoom-us "$@"

A version which wouldn't actually install anything (probably via nix-shell) would even be better.

This appears to be working for me as of my latest upgrade on nixos-unstable.

zoom-us worked fine for me until recently; even though the version didn't change, all I am getting now is a blank UI.

I am also getting a blank UI:

y-11-30-195323

I get the same results with the following methods:

  • nix-env -i zoom-us
  • The above script
  • NIXPKGS_ALLOW_UNFREE=1 nix run -f https://github.com/nixos/nixpkgs/archive/master.tar.gz -u PATH zoom-us -c zoom-us

Environment info:

 - system: `"x86_64-linux"`
 - host os: `Linux 4.14.83, NixOS, 18.09.1420.5d4a1a3897e (Jellyfish)`
 - multi-user?: `yes`
 - sandbox: `yes`
 - version: `nix-env (Nix) 2.1.3`
 - channels(shosti): `"nixos-18.09-18.09.932.09195057114"`
 - channels(root): `"nixos-18.09.1420.5d4a1a3897e"`
 - nixpkgs: `/nix/var/nix/profiles/per-user/root/channels/nixos`

@shosti can you try this?

$ nix-env -p zoom-dedicated -i -- nix zoom-us
$ nix-env --switch-profile zoom-dedicated
$ sudo -u $(whoami) env PATH=$PWD/zoom-dedicated/bin zoom-us

Just to be sure environment doesn't influence zoom. To switch to your original profile

$ nix-env --switch-profile /nix/var/nix/profiles/per-user/$(whoami)/profile

@danbst effected by the same issue. Tried the suggested steps above, still see @shosti 's screenshot.

 - system: `"x86_64-linux"`
 - host os: `Linux 4.18.16, NixOS, 18.09.git.b041bfefbc8 (Jellyfish)`
 - multi-user?: `yes`
 - sandbox: `yes`
 - version: `nix-env (Nix) 2.1.3`
 - channels(root): `"home-manager, nixos-19.03pre158246.6141939d6e0"`
 - channels(flokli): `"nixpkgs-19.03pre157960.722fcbbb80b"`
 - nixpkgs: `/home/flokli/.nix-defexpr/channels/nixpkgs`

(I rebuild with -I nixpkgs pointing to channels/nixos-18.09 (db561c90ef34cc64287ee1c366ab9eec85b2af50)), and passed the channels tarball to nix-env when trying what @danbst suggested)

can you run $(nix-store --realize /nix/store/cg3ap83g7gidwi39qda65i94slivmjbk-zoom-us-2.4.129780.0915)/bin/zoom-us? this version is working for me

@flokli the difference between your output log and mine shows, that I have gnome desktop manager and you don't have it. Linux kernel and zoom version are same.

Can you try temporarily switch desktop manager to gnome and check if zoom works with gnome?
Also, try to clear ~/.zoom and ~/.config/zoomus.conf (with backups, obviously).

@zimbatm no idea how to realize, as it's unfree and not shipped via the NixOS cache…
I'm currently on /nix/store/nhvaarg08yx3n4mf6pghi4qvww8lq1xf-zoom-us-2.4.129780.0915/bin/zoom-us, if that helps…

I will check if it works in a gnome environment in a bit.

I switched to a gnome profile, first I still saw the screenshot from above.

I then started suspecting the video driver, played around with mesas env vars, used LIBGL_ALWAYS_SOFTWARE=1 and suddenly it worked.

Annoyingly, I now can't get it back to not working, tried cleaning .cache/zoom, .cache/qtshadercache and .zoom, but there must be some other state file lying around somewhere, or broken state, that got fixed up while switching to the software renderer.

So it works now :man_shrugging:, @shosti can you try to reproduce, while keeping a close look at files updated while opening zoom then?

I don't run a DE. What @flokli suggested fixes the rendering issue, but only if I run it from a terminal with that parameter set.

Setting LIBGL_ALWAYS_SOFTWARE works for me as well.

It seems multiple people are affected - @danbst, what graphics card are you using? Maybe it's a driver problem…

What's your opinion on setting LIBGL_ALWAYS_SOFTWARE by default, like @yrashk did in https://github.com/yrashk/nix-home/commit/19bf8690b39e9d5747823dfbefee8d7e801205e1? It might be a performance hit, but better than the application not working for half of the users…

Also opened a support request at Zoom, and pointed them to this issue - maybe they have better ways to debug it, as they know how their software does opengl…

I would also check your Mesa shader cache in ~/.cache/mesa_shader_cache as
sometimes a Mesa upgrade can leave the cache unusable. Just deleting or
renaming the directory is fine.

@tadfisher clearing mesa shader cache didn't work unfortunately.

zoom-us-2.6.146750.1204 looks a bit different on startup (now the lower window part is just blank) instead of showing the"Join a Meeting" / "Sign In" buttons and version information.

I'm seeing the same as @flokli now. The only thing I think has changed on my end is the switch to Wayland for the default Gnome session.

@flokli I don't want to include LIBGL_ALWAYS_SOFTWARE=1 by default. The problem is in computer setup, not this package. Let's hope google will point to this page for ones who struggle.

@tadfisher can you open new issue for this? Zoom from master (recently updated) works for me.

@danbst interestingly, switching to unstable fixed it on my machine as well.

Simply bumping zoom to 2.7.162522.0121 on 18.09 wasn't enough to fix it there.

Any idea how this could have been fixed? I'm curious ;-)

@flokli How did you do the bump previously? Haven't you mixed up Qt? I've had a coredump recently due to this problem https://github.com/NixOS/nixpkgs/pull/54969

@danbst basically, backported #54969 into my 18.09 checkout (or in that case, another variant provided by zoom's support logging much more), then switching my system to it.

Simply running from result/bin/zoom-os led the same segfault. But this error is something most likely fixed by setting QT_PLUGIN_PATH in a wrapper, using the wrapper provided by #54525 or merging #44047, which fixes this inside qt (preferred by me ;-) )

I was more interested in why the UI isn't blank anymore with zoom-us on unstable. My current guess was differing qt versions, was assuming you did dig a bit deeper ;-)

@flokli then it might be unstable fixed your video drivers issue. If you have enough time you can git bisect it down to commit which makes it work.

Might be - I think I'll just leave the proof as an exercise to possible other interested readers ;-)
