        Date: 2022-04-04 21:09:23 +0000

Issue/Bug Description:

Only the mouse pointer is shown when screen sharing, everything else is black.

Steps to reproduce (if you know):

Switch to hybrid graphics mode
Reboot
Open slack
Start a huddle
Hit share screen

Expected behavior: I should be able to share my screen.

Environment:

Chromium Version 100.0.4896.127 (Official Build) (64-bit)

NVidia 940mx ➜ ~ nvidia-smi

NVIDIA-SMI 470.86       Driver Version: 470.86       CUDA Version: 11.4

Other Notes: Important:

It works in integrated graphics mode.
Screen sharing works in both integrated and hybrid mode when testing in mozilla's webrtc test page (running chromium Version 100.0.4896.127 (Official Build) (64-bit))
I am running Wayland.

I am running Wayland.

Wayland + screensharing is still a bit iffy. Xorg is still default on Pop!_OS.

Noted. I'll switch back to the integrated graphics mode as I don't really need the dedicated GPU anyway.

Should this be closed as an upstream bug that we won't fix?
