I have a sapphire r9 390. I currently have crimson 16.11.4 installed. When i attempt to upgrade to 16.12.2, i end up getting horizontal lines all over my screen that move everywhere (appearing and disappearing over and over) which stop once i attempt to update to the optional update (which never launches, only brings loading circle). When i uninstall this driver and revert top 16.11.4, the issue is gone. Any suggestions?
