Window Capture is a Black Screen for games and Steam

[TheMonologueGuy]

Screen Capture works fine and game capture works just fine under Windows. This problem persists with the PPA, snap, and flatpak versions of the app.

I've included my latest logs. From what I can tell, the error seems to be related to this:

xcompcap: glXCreatePixmap failed: BadAlloc (insufficient resources for operation)

I found a workaround:
Setting the game in windowed mode allows the feed to show up in Window Capture. I've only tested it on one game so far, but this is what worked for me.

Sidenote:
During my troubleshooting, I tested Xonotic flatpak and discovered the game showed up in Window Capture without any issues. As of now, the issue appears to be isolated to Steam and its games.
