[Wayland] All games launch to a black screen with DISPLAY env var set

[C0rn3j]

This is the remaining issue from the now-closed #1045.

Running the emulator on a Wayland compositor with a set DISPLAY environment variable causes all games launch with a black screen.

unset DISPLAY; shadps4 is a workaround.

Seem to be NVidia driver issue. I can run under XWayland on the Intel iGPU.

With Vulkan Sync Validation enabled, I got these when run the emulator on NVidia/XWayland, not on Intel/XWayland:
