apparently, you can't actually trust OBS on Linux to even record a basic video properly. it just outputs a garbled video. it looked fine in the preview while i was recording it. i tried converting from MKV to MP4 using FFMPEG and it still looks garbled, so it's definitely OBS that's fucking up here. oh, and it also randomly crashed one time while i was configuring it, so it's not very stable either... 🙄
