SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***


STEPS TO REPRODUCE
1. Install Xwayland Videobridge on Arch (from Source or AUR)
2. Launch Xwayland Videobridge

OBSERVED RESULT

On Nvidia: Error Message "libEGL warning: egl: failed to create dri2 screen"
On AMD: No Output in Console

On Both:
The Window is visible and shows up in Taskbar. No Selection Window is shown when trying to share screen (e.g. in Discord). When selected for sharing, only a white screen is streamed.

EXPECTED RESULT

Window should be hidden, a selection should pop up when starting to stream, stream should show the actual content of what's streamed

Comment 2 David Edmundson 2023-06-17 10:42:04 UTC 
Can you confirm if screen sharing in other applications work? 

this page in firefox is a good test: https://www.webrtc-experiment.com/Pluginfree-Screen-Sharing/#8149214815066223
Comment 3 David Edmundson 2023-06-17 10:44:05 UTC 
Edit, it's broken for me too
Comment 4 David Edmundson 2023-06-17 11:02:48 UTC 
My released flatpak still works as intended. 

Checking out xwaylandvideo bridge at the same commit as the released flatpak does not work.
Comment 5 Daniel Skorupa 2023-06-17 17:13:49 UTC 
It stopped working for me too today, debian 12. I've installed it yesterday and it worked. It's exatly the same as you describe - only white rectandle and it doesn't ask which window / screen do I want to share.
