Webgpu not working with 7900xtx and Ubuntu 22.04

I have an issue with hardware acceleration in browsers.

chrome://gpu returns "Disabled" or "Software only, hardware acceleration unavailable" for most of the features.

As a result WebGpu is not working and WebGL is using CPU only.

Added details in an earlier post but got marked as spam, so for now I just wonder if anyone has this particular setup working at all (Linux or Windows), or if this is a known issue

Driver version is 5.5.50502 and works fine in native applications like Blender and Godot.

Some update. The hardware acceleration problem was solved by using open drivers instead of proprietary i.e from this:

sudo amdgpu-install --usecase=workstation,rocm,hip -y --vulkan=pro --opencl=legacy

to

sudo amdgpu-install --usecase=graphics,rocm,hip -y --vulkan=amdvlk --opencl=rocr

However webgpu does still not work, but that seems to be related to development status of webgpu on the Linux version of the browsers

According to https://github.com/gpuweb/gpuweb/wiki/Implementation-Status it is only supported in nightly builds of browers like Chrome or Firefox. I tried Firefox nightly and webgpu still failed but I do not believe it is related to AMD drivers.
