qtile: Wayland: Signal-desktop with wayland flags does not open

Issue description

Signal-desktop started with

signal-desktop --enable-features=UseOzonePlatform --ozone-platform=wayland

does not open on the wayland backend. It does when using sway (It actually is native wayland, verified with xeyes so it’s not because of a lack of Xwayland support in qtile). There seems to be an issue with setting the wid of the window (see stack trace obtained from running in a nested session). Chromium with the same flags works fine. So does vscode with those flags, so not all electron apps seem to be affected. I am trying to debug it in the meantime but I’m not very experienced with the wayland code.

Btw I love how smooth qtile works under wayland, great work!

Edit: Hmmm, those wid errors seem to happen on other windows too. But they only happen when I run Qtile in a nested session AFAICT, so I’m not sure what the issue is with signal-desktop not starting. In a normal session it also does not start and ~/.local/share/qtile/qtile.log shows the top 5 lines before the wid errors in the stack trace I provided.

OK I have been an idiot!

I run Qtile with the master version of wlroots from their git repository, rather than from a package, so that I can keep abreast of their changes and make changes to pywlroots accordingly. Checking out their 0.14.1 tag and rebuilding, signal-desktop works with your patch!

The edges are like that because that commented line tells clients that their windows are being tiled on all 4 edges and they’ll do things like have 90 degree corners (some clients will otherwise round them).

I’m at a loss currently do decided to just download and build signal-desktop and find out that way!

@m-col I am trying to debug it right now and it does work in tinywl and tinywl from pywlroots. So I just started trying random things and the following patch makes signal-desktop appear for me. I’m not sure why as I’m not that experienced with wayland stuff. Any reason why this works for me 👀

EDIT: This also solves vscode not opening so it seems to fix it for electron apps. Any reason why that was needed? As a quick test things seem to work in wephyr.
