Intel Arc B580 Visual Artifacts Issue

I am getting visual artifacts in some applications in Cachyos


Video example of visual artifacts:

This happened in Bazzite and now CachyOS.

Happens only in some applications. So far Handbrake, ptyxis terminal, LACT and a few others.

Consistent over several updates to CachyOS. Versions shown at end of video.

Everything left default for kernel, gpu etc. Only tried different display settings.

Apologies if issue raised incorrectly. Almost everything is working perfectly in CachyOS. Really liking it so far, just a few apps having visual problems. *** I couldn't make an account on the forum to post it there 🫣

Start by reproducing the artifacts in HandBrake, Ptyxis, LACT, and the other affected applications under KDE Plasma, KWin, and Wayland. Compare the reported CachyOS kernel, Mesa, GPU, and display details while testing the affected applications; done means identifying a reproducible scope and an actionable cause or fix.
