Current Behavior

OS: Ubuntu 24.04 (Proxmox VM)
Docker Deployment.
Nvidia P400 pass through

Upon upgrading Dolphin Docker Image from (amd64-version-f2f0826e) to ([amd64-version-fc8072bc], when a game is launched, the dolphin container stalls and causes significant spikes in Drive IO (Read & Write at about 200MB/s). Game does not deploy successfully.

Expected Behavior

No response

Steps To Reproduce

Upgrade from container image (amd64-version-f2f0826e) to (amd64-version-fc8072bc) on ubuntu 24.04 with nvidia p400 (or similar gpu) and game will stall.

You can revert to X11 if that worked better for you with -e PIXELFLUX_WAYLAND=false, just a heads up. Nvidia in wayland has new requirements as laid out in the readme.
