Is this a problem with the screen refresh rate? Or it was interrupted by other interrupts before the refresh was completed(This is my guess, I don’t know how to locate this problem)
I’ve seen these types of artifacts appear when the CPU cache is enabled but not managed properly; are you doing anything relating to that?
