Crash Report

Looks like a more severe version of #2625. We know there's multiple things that can cause these artifacts.

EDIT: I started work on a separate branch for fixing these issues, please use this nightly link instead and see if it helps with the issue. Thanks.

Can you see if the latest nightly fixes this problem? We made some changes recently that may help.

@jellysquid3 The rendering issue is fixed with your branch! Thanks for supporting a decade-old iGPU. 🥳
I can't promise there isn't any regression hidden though, so just tell me if you want additional manual testing.

I made some more changes that were needed to accommodate GPUs with only 12.4 texture coordinate precision. This should include your graphics card. Can you make sure this build still works correctly on your computer?

Hi! Just wanted to confirm, the v2 build still worked.

Fixed with 50325dd.
