amdgpu crash when screensharing on Linux with canary version

(#3694) Bug Needs triage

Observed behaviour

When screensharing for around 15 seconds or so, all my screens turn black as the amd driver seems to crash.

Reproduction steps

  1. Download canary flatpak version (flatpak install --from https://pkgs.fluxer.com/flatpak/fluxer-canary.flatpakref)
  2. Join a voice channel
  3. Share your screen (I used full desktop & selected my secondary screen)
  4. Just wait around, you may need to click on the fluxer window & drag some windows around on the other screen
  5. Everything crashes.
