[information] Nvidia Gnome Wayland - OBS bugged-stuttered 1FPS capture

[danilw]

Nvidia 570.124 Gnome 47 Wayland OBS 31.01

When I try recording of wine-proton(does not matter)-game using OBS - with vkcapture or without - with just basic CPU encoding and full screen capture is same.

Bugged result is - <1FPS video when "game" become visible on screen (there just random frames, does not matter if game is in window or fullscreen)

Fix:

• run game with OBS_VKCAPTURE=1 (this obs-vkcapture should be added to OBS to have it work) (add in Lutris - game settings system parameters env variables menu)
• run OBS in gamescope (adding game capture in OBS) gamescope -b -W 1280 -H 720 -w 1280 -h 720 -r 60 -- obs
• after that - 60fps lagless recording (with NVENC everything works same as before)

Just for information.

I think reason for this behavior - is Gnome 47 in Wayland somehow "stop rendering process" for all apps that is not visible on screen. And when OBS start recording - it on other desktop or even alt-tab not visible - it may be OBS issue or Gnome.

(im on kernel 6.13.5 I tried to downgrade to 565 drivers to test but they not work with this kernel - and looking on other apps behavior - it not just OBS - other apps also "frozen" when no visible - most likely this is not driver issue but new Gnome on Wayland behavior)
