I have a Windows 7 setup with 2 AMD 7970 card and with cgminer version 2.10.4 running I get little chunks of small black boxes flashing around the edges of windows. Is this normal or are the cards bad? I don’t seem to have trouble in games or anything else but nothing else maxes the two GPUs at 97-99%.
If I do run a game at the same time some are ok but one game has stuff all over the screen unless I turn off cgminer. It’s odd as the games seem to run ok speed wise with cgminer but of course the hash rates go down. Makes me think the cards passed some minimum QA test but are not 100% fully stable if a game used 90%+ of the GPU.
No overclocking and the temps all look good.
