I have the same problem with Intel UHD Graphics 620.

On the same setup Arch distribution is working fine https://github.com/yuk7/ArchWSL. So this is a distribution specific issue

This is because archlinux doesn't include vgpu support by default. After installing a custom version of mesa with d3d12 support, the output becomes blank, too. So this is a issue related to intel graphics driver. Many programs depending on opengl don't work properly.

Reopening issue as accelerated rendering via vGPU is still blank

I reiterate the same problem with Xe Graphic card, obviously, it is a common problem for intel GPU. I suggest changing the title of the issue, as it is a common problem regardless of the specific graphic product.

Bump. Workaround to get at least some output:
LIBGL_ALWAYS_SOFTWARE=1 glxgears

Looks like the latest Intel Graphics Driver 30.0.101.1404, 2022-03-08 finally fixes the issue.
Tested on latest Windows 11, Ubuntu 20.04, Mesa 21.3.7 (kisak-mesa stable PPA).
