My monitor has a buggy firmware that causes sway to detect my monitor as unplugged when it wakes up from sleep.
If I switch scenes to the wlrobs after a wakeup, OBS crashes, it doesn't safely handle a missing display, and probably needs to check that the handle hasn't disappeared?
I'll have to figure out how to reliably reproduce without waiting 5-10mins every time, because I can give a stack trace of the error.
This has been fixed for dmabuf by...OH LOL. It's you...I just forgot about this...welp...it's fixed by f72d5cb3cbbd. Thanks for the email poke. I have not fixed screencopy yet.
