Thanks for the bug report. It's certainly a crash, but not one I've seen before:

Steam has its own "Game Recording" feature which is capturing video and audio, and then OBS also is capturing video and audio. At some point, not long after the two are started, I get a white screen stating that something went wrong and I need to log out. I will attach the relevant bits from my "journalctl --user" log, which is unfortunately not much.
