I get a lot of visual artifacts when first opening Chromium on Pop!_OS with a 12th gen intel Framework laptop. Relatedly, odd black outlines will appear around different elements around the OS occasionally. I believe I’m on the most recent drivers and such, is there some other configuration necessary to fix this bit of cruft?
I saw something similar to this on an intel Mac running canary years back. I believe toggling GPU acceleration in the settings resolved the issue.
