Got Radeon R9 270 for like 10 months now this started recently. Had some wierd glitching in games but restart was helping until now. Deffinitly nothing with my screen neither conection since it happens more if i highlight something like for example in my mobile photo in Catalyst. Should I go str8 for guarantee or it might be some softwere issue? It happens while 40 celcius and barely any use at all.
