I got a strange screen flicker from time to time. Happens randomly while watching videos, starting applications or browsing in kodi. Comes for an eyeblink (green or red flickering)
Happens with all crimson drivers even with latest 16.11.4 on my RX480 8GB. Tried with different Displays and cables. Running UHD resolution to my UHD TV via HDMI using 2.0a certified cables
I made a short .mov file which shows the flicker. Can send it if support wants it.
