Comment # 5 on bug 71226 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.
