Bug 489777

Created attachment 171403 [details]
Left: Latest version (not showing up), right: old version before the commit mentioned

***
The latest build from cdn.kde.org (date: 2024-06-26) no longer shows up in Discord as an application. 

The issue appears to be happening since this commit: https://invent.kde.org/system/xwaylandvideobridge/-/commit/9d7e44433f6bc62bb2bcc58f56774fe8d54ba841

I build a version from the commit right before it, and it started working again perfectly.

ADDITIONAL INFORMATION
Discord made a change where they are running on wayland now, trying to screenshare will open their selector and spam the OS prompt but it will never actually work. To work around that add the following variable (using flatsail or something like that) when using Discord as a flatpak: XDG_SESSION_TYPE=x11
