Hi! Have you also tried to take a screenshot with Gimp. using the "Select whole Screen" option?
I'm asking because I have a corruption that looks similar to your screenshot and could be fixed by ColorTiling=off, but I was able take a screenshot with the Gimp, and I'd like to know whether it's the same issue. I can see this issue after returning from some screen-resing game (I'Ve tried ppracer). The issue also occurs when I manually resize my screen with xrandr ("1280x1024" > "800x600" > "1280x1024"), but then the corruption is not immeadiatly visible.
