Cannot capture on NVIDIA wayland

[kakra]

Describe the bug
With NVIDIA on KDE Plasma wayland, obs-vkcapture sees the window and I can select it from the dropdown but it won't capture the contents. Additionally, OBS uses almost all cores of my CPU, but I didn't test yet if this behavior goes away with disabling obs-vkcapture.

System (please complete the following information):

• OS: Gentoo Linux
• GPU: NVIDIA RTX 3080 Ti
• Mesa version:
• obs-vkcapture version: git-latest 2024-07-27

OBS log:
2024-07-27 23-08-15.txt

Game log:
Not available.

It works with X11. And OBS also works with pipewire-capture instead.

This may be specific to NVIDIA due to limited dmabuf support.
