Nightly does not work with ozone (wayland native)

[HarHarLinks]

Steps to reproduce

Stable supports running in wayland native like this: element-desktop --enable-features=UseOzonePlatform --ozone-platform=wayland. Doing the same with element-desktop-nightly apparently does not. Maybe because bundles its own electron (assumption based on no dependency in the pkg)?

This is on sway 1.6.1.

What happened?

What did you expect?

element works as usual

What happened?

no window, only the indicator icon appears.

Operating system

arch

Application version

Element Nightly version: 2021090301 Olm version: 3.2.3

How did you install the app?

aur/element-desktop-nightly-bin

Homeserver

own

Have you submitted a rageshake?

No

This isn't one of our packages I'm afraid - I'm not sure we can really help much unless it's just a case of it using a different electron version or something perhaps? Although we are fairly up to date.

[HarHarLinks]

I realize that this package isn't strictly provided to aur by element, but looking at the pkgbuild https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=element-desktop-nightly-bin it really is just the packages.riot.im .deb nightly. Isn't that yours?

Perhaps this was caused by element-hq/element-desktop#256 as @yu-re-ka suggests in element-hq/element-desktop#256 (comment). @yu-re-ka, what leads you to think that was the change that broke Element with Wayland?

[SimonBrandner]

@yu-re-ka and @HarHarLinks, does the Jitsi desktop app work for you?

[yu-re-ka]

The described failure mode matches what I have observed.

element-hq/element-desktop#256 adds a --enable-features WebRTCPipeWireCapturer flag to the electron cmdline. However @HarHarLinks and I set this flag as well, so effectively electron gets started with --enable-features WebRTCPipeWireCapturer --enable-features UseOzonePlatform and Chromium/Electron don't support passing the flag multiple times.

This should be fixed by element-hq/element-desktop#261, but the build date of the nightly package suggests it doesn't include the fix.
The Jitsi desktop app had the same problem.

[SimonBrandner]

Ah, great thanks for the explanation! Let's assume this is fixed now. Let me know if you ever see this again

[HarHarLinks]

It does seem to work in principle now. I'm noticing a last small problem: when running with ozone, the window_properties field is missing. This contains a bunch of meta info to identify the program and is commonly used to e.g. assign apps to fixed workspaces. Consequently my condition that moves windows with class beginning in Element to a certain workspace.
get_tree with ozone:
