Screenshots are from the female character prologue when you start a new game, but there's a lot of sprites everywhere in this game.

Attach capture files for visual issues

We also tried to force hw msaa resolve, and it didn't change anything.
There are no warnings in the log, so I assume it's a RADV issue, maybe recent driver regression.

I tried to test myself on zen5 igpu, but radv segfaults on fedora 41, and llvmpipe/nvidia drivers work fine.
