Expected behavior:

No response

Actual behavior:

when i use WAYLAND_DISPLAY=0 It works but if i quit the program, Segmentation Fault also shows. It did't fault in /usr/lib/wsl/lib/libd3d12core.so

WSL2 is not a supported scenario and it looks like the issue is in /usr/lib/wsl/lib/libd3d12core.so. You better report the issue to the wslg project.

without WAYLAND_DISPLAY=0 the example will fault in /usr/lib/wsl/lib/libd3d12core.so and didn't work properly
