Workaround:
Disable scatter gather support on kernel cli and increase the reserved VRAM.
Known issues with the amdgpu default enabling of Scatter Gather VRAM which is set from 6.2 kernel onwards.
add
```
amdgpu.sg_display=0
```
to your Kernel command line, and change the VRAM allocation in the BIOS to
```
UMA_GAME_OPTIMIZED
```
These in combination alleviate (but not completely remove) the issue you are seeing.
