Bug ID: 488560
Summary: OBS shows an encoding error using NVENC with NVIDIA
GTX 1060 under Wayland with pipewire
Classification: Plasma
Product: kwin
Version: master
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: screencasting
Assignee: kwin-bugs-n...@kde.org

Nvidia bug report
STEPS TO REPRODUCE
1. Use NVIDIA drivers 555 from the AUR
2. Use plasma 6.0.90 from the official Arch repositories
3. Use Arch extra repo's OBS package with all optional dependencies and try to
record using NVENC as the preferred encoder
OBSERVED RESULT
When trying to record the full screen with NVIDIA graphics under wayland on
Plasma 6.0.90 there is an error that happens when minimizing OBS to the
background while recording, the logs of OBS when running through Konsole say:
