My client has a Radeon R5 340x on his W10-64bit system, and, a little while back, Windows Update installed the infamous 1803 version. He began to notice screen glitches. Device Manager lists the driver version as 23.20.806.256, but the Radeon upgrade tools describe the version as 17.7. I cannot roll back the driver from Device Manager, as that button is grayed out. I tried several newer versions of the Adrenalin driver, but all of these generated error 184 - Unsupported OS version. What is the best way to proceed?
