I wasn't sure whether to post this here or in the graphics board but it seems to be related to the driver update.
I have an MSI R7850 and ever since I updated to the new Radeon drivers (16.4.2) I've been having some issues with graphical artifacts/glitches and the display driver crashing pretty often. I also got some blue screens but I haven't got those recently and didn't note down the codes (sorry). I've attached a picture of one of the graphics glitches they are happening all the time. Here's some info about the other components in my system if you need anything else just ask, thanks for your help.
