--- Comment #8 from Rafał Miłecki zajec5@gmail.com --- (In reply to comment #7)
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.
