[Bug]: gamescope with NVidia Optimus fails to display anything on the host

[mrsteyk]

Describe the bug

When using gamescope feature with discrete gpu option enabled (Intel+NVidia configuration) under Wayland, gamescope reliably fails to make a window on the host to display anything.

To Reproduce

1. Go to bottle's settings
2. Make sure discrete gpu and gamescope are enabled
3. Run any application

Package

Flatpak from Flathub

Additional context

This was tested under sway, labwc and weston. Using prime-run to launch compositors didn't help. Log attached is from running a game launcher, when running game itself same "no gamescope window" thing happens, but you can hear the sound. nvidia_drm.modeset=1 is set in bootloader. Needless to say it works if you disable the discrete gpu feature, but imagery is distorted (doesn't happen when manually running with --command=/bin/bash and WINEPREFIX=~/.var/app/com.usebottles.bottles/data/bottles/bottles/X/ gamescope -f -w 1920.0 -h 1080.0 -W 1920.0 -H 1080.0 -- /home/mrsteyk/.var/app/com.usebottles.bottles/data/bottles/runners/soda-7.0-9/bin/wine64 GAME)

[mrsteyk]

If "distorted imagery" piques your interest (bg video works on discrete)

[xlacroixx]

Not using NOVIDEO Optimus, as I am on a desktop with GTX 1060 6GB, but I had the same issue (no window with gamescope and app in background).

Followed this workaround; gamescope now pops up.

Basically, try to run bottles with (assuming Flatpak): flatpak run --env=GBM_BACKENDS_PATH=/usr/lib/x86_64-linux-gnu/GL/nvidia-XXX-YY-ZZ/extra/gbm com.usebottles.bottles

Replace nvidia-XXX-YY-ZZ with the version you find by running flatpak run --command=ls com.usebottles.bottles /usr/lib/x86_64-linux-gnu/GL.

I recommend you try to run it again now with the new drivers, I couldn't even play with gamescope enabled now it seems to be working
