After leaving perfectly working display for ~15 minutes, coming back and leaving screensaver I got that broken colors on panel display.

--- 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.

It seems to only show up in apps that use OpenGL and only after a suspend/resume cycle.

If it only happens in OpenGL apps, that indicates a problem in the 3D rendering pipeline.

I'm not using a desktop compositor, so i never see it affect the whole screen like Rafał's screenshots.

Actually, my assumption from Rafał's description was that he's only seeing the problem on one of several connected displays at a time, which would indicate a problem in the display pipeline instead (assuming all displays are showing the same contents or are all updating their contents while the problem occurs). Rafał, is my assumption correct?

That's right. I got wrong colors on HDMI-0 while everything was fine on eDP at the same time.

That's usually indicative of the monitor not dealing with the HDMI packets from the GPU properly. E.g., the monitor may think it's getting YUV data rather than RGB. Disabling hdmi mode (driving the display like DVI) should avoid the problem if that's the issue (e.g., radeon.audio=0).
