Weird graphical glitches on textures in the viewport

[Ilia5C31]

Textures in the project look corrupted when I open a project with UDIMs 

this looks like incorrect projection of UVs

If I change resolution to any other, then textures regenerate and everything looks fine, till i start woking.

Then, when using a fill layer from time to time textures get corrupted again. Example: normal map not rendering, roughness looks wrong i.e. incorrect, normal map in wrong places of the mesh.

Recalculating textures by changing resolution fixes it for a while, but then everything breaks again.

Painter Ver. 9.0

What I did to fix it: reinstall painer, rallback AMD graphic driver, disable sparce virtual texture hardware acceleration. Check on a different project that worked fine before (same issue, except with one UV tile the project is loading ok, but then during adding fill layer graphical glithes occur).

Have no clue what is wrong and where the error is.

Any help?

UPD.

Looks like rolling back from 23.7.1 to 23.5.2 actually worked. So far didn't notice anything weird except for when I opened the project. Which probably was old cache with artefacts.

Hi @Ilia5C31,

This is weird. If you're facing this problem once again, I'd love to take a look at your log (Help>Export log...) and the project (.SPP) itself. So feel free to share it at cdellenbach@adobe.com

Best regards,

Thank you.
