Make sure you don't have "half-rate shading" turned on the the deck battery settings. I do see a protondb report with similar issues, but everywhere else I see the game discussed no one seems to be complaining about it.
Oh shit, that was turned on. No idea why it was though, as I normally use per-game profiles. Thanks for the suggestion!
Should edit your post with the solution so others can see!
You're not an idiot, I had the same issue with last epoch and it took me a while to understand. Half rate shadering has no side effects on most games so I didn't see this coming ๐โโ๏ธ
Wait, it actually does something?
Try setting it to use proton experimental, newer games sometimes depend on features that aren't in the stable versions of proton yet (or are at least buggier/worse in the stable versions)
Edit: also try launching the game from desktop mode. The compositor in steam mode is Wayland-based and desktop mode uses an X11 session by default. The issues you're describing sound a bit like something that's happened to me running games under Wayland on my laptop
