--- Comment #5 from abortretryfail@gmail.com --- I'm having a very similar problem on my BARTS XT.
It seems to only show up in apps that use OpenGL and only after a suspend/resume cycle. I'm not using a desktop compositor, so i never see it affect the whole screen like Rafał's screenshots.
Colors appear to invert or brighten randomly then go back to normal a couple seconds later. Similar to the attached jpegs.
