Having issue with 64-bit Linux Mint 20.1, Cinnamon and OBS 26.1.1. Some windows with XComposite are black (desktop, web browser Brave, Chromium, etc.), some visible (terminal, Thunderbird, System settings, file manager, etc.). At the same time desktop with XHSM is working fine.
Having nVidia Quadro M2000M (GM107GLM). Allow flipping is disabled - didn’t help. Also that alpha channel Mesa solution option under XComposite settings didn’t help.
nvidia-xconfig --composite
didn’t help either :(

Another similar issue:
This issue is outlined in detail over in GitHub in this issue: Black preview screen in Linux Mint · Issue #4259 · obsproject/obs-studio · GitHub
It seems like many users are experiencing this issue, But the TL;DR:
Having a nVIDIA Ge Force 1080Ti with the latest drivers (460) and when I load OBS (v26.1.1) a black screen appears with no preview available (screenshot linked below).
None of the steps mentioned in the issue work. Is there a way to fix this? If not, is this a known bug that’s being worked on? Seems like it was a known issue here but the fix doesn’t seem to have helped all cards: Linux Display Driver - x86 | 340.108 | Linux 32-bit | NVIDIA
