pacman -S mesa mesa-utils
glxgears

check on windows taskmanager to see if the gpu is being used.

Expected Behavior

the gpu is used to render glxgears

Actual Behavior

glxgears is rendered using cpu

I am not able to reproduce this.

forgot to mention that i am on intel integrated graphics, the intel gpu info only shows up on ubuntu:

Irrespective of the GPU being amd/intel/nvidia, it should work as long as you have the correct drivers installed

[LuanVSO]

i re-installed the distro and only installed the mesa packages, it still doesn't work, do you have any pointers/tips on how to debug this?

This is important. Intel graphic cards (I use Iris Xe) only work in Ubuntu (not even in Debian/Devuan) in my experience with 15+ WSL distros, i.e. it's not limited to Manjaro but more of a upstream issue.

It used to work but a recent kernel/WSL package update breaks it again. It's reported in microsoft/WSL and I suggest you taking a look at Ubuntu's hack to make it work.

Link me to it

Sorry, I just recall it and can't remember the source... But I can point you some links that may help:

1. WDDM GPU Paravirtualization support for WSL2: general guide
2. Configure the host to bind vfio-pci to Intel Iris Xe: more detailed but maybe exclusive to Linux desktop or Iris Xe, no idea whether it applies to WSL or UHD. It involves compiling the kernel if earlier than Ubuntu 22.10

Basically it's either vGPU driver not installed/working or kernel w/o the driver adapter enabled.
