See is this helps.

TLDR: flatpak run org.signal.Signal --enable-features=UseOzonePlatform --ozone-platform=wayland [+ socket access override if needed].

Nvidia?

[alvarlagerlof]

Shouldn't I work by default? Setting env vars is not nice. Yes, Nvidia.

[vchernin]

What distro? Make sure xwayland is up to date (21.1.3 or later iirc). It needed Nvidia-specific fixes for some xwayland apps to work.

[alvarlagerlof]

I don't think I have completely the latest, it's fedora 35. Will get GBM in a couple of days but this app was broken while other election apps worked, so I figured it was more likely incorrect options.

[vchernin]

You could try different options, but with GBM imminent it might be best just to wait.

[alvarlagerlof]

Yeah that might just fix it anyways. Will come back and report on it when it works/doesn't in a few days.

[alvarlagerlof]

The issue does not seem to be in the not in the drivers. I am now on 510 and the issue persists. GBM is supposed to have been working for a while. Using --disable-gpu-sandbox makes the app work.

razzeee/im.riot.Riot@2b9214a this might fix it

[abique]

Maybe it did not make it yet to flathub?
Also I saw in flatseal that signal does not have dri access by default?

[vchernin]

By default Signal has --device=all which includes --device=dri

[abique]

So it is a display thing in flatseal then.

Can you test #277 ?

flatpak install --user https://dl.flathub.org/build-repo/77479/org.signal.Signal.flatpakref

That just 404s, but --disable-gpu-sandbox did not work for me manually.

I'm using the latest signal from flatpak and for me the bug is now fixed.

It is indeed for me too.
