xcompcap: no matching fb config found

[tdkuehnel]

Dear,

my working OBS Studio - 24.0.6 (linux) installation is no longer able to use a firefox browser window as a source, as firefox updated to 82.0 in the background thanks to mozilla for the auto-update feature.

Launching obs by hand gives lots of

...
error: xcompcap: no matching fb config found
error: xcompcap: no matching fb config found
error: xcompcap: no matching fb config found
error: xcompcap: no matching fb config found

lines. When activating a working window as a source it gives:
...
error: xcompcap: no matching fb config found
info: xcompcap: [window-capture: 'Fensteraufnahme (Xcomposite)'] update settings:
title: Telegram (445)
class: Telegram
Bit depth: 24
Found proper GLXFBConfig (in 14): yes


What to do to make OBS happy with updated firefox on Gnu/Linux ?

The same problem occurs in OBS 25.0.8 (Linux). I recently upgraded to Firefox 83.0. When I attempt to capture a Firefox window, I get

  error: xcompcap: no matching fb config found

Suggestions to getting it working with Firefox would be much appreciated.
