NPUB31848 artifacts in menu

In that case, I'm terribly sorry for bothering you. I did see the part about driver updates in the "how to ask for help guide", But assumed it was up to date when the amd app said it is.

I find their driver download page terribly confusing especially since the auto-detect says your os is unsupported. (While windows 8.1's EOL is January 2023)
I will report back when I managed to update it to say if that fixed it or not.

Thanks for your time.

I just managed to update it with great difficulty (apparently there is no installer for version 20 despite it working perfectly fine on win 8.1), and it runs with Vulkan. I haven't noticed any artifacts so far.

For future reference (in case someone else hit here), I used this to update the driver: https://community.amd.com/thread/246796
I had to run the win 7 installer, then press close when it said my os is not supported, then tell device manager where it extracted its files so it can install it anyway. Because apparently windows 7 is newer than 8.1, so it should get updates while 8.1 doesn't...

Sorry again for wasting your time on user error.
