Forgot to mention I'm using GUIminer and also briefly tried CGminer but saw the same kind of artifacting.

Yeah that can happen while mining, doesn't mean there's anything wrong. You can decrease the intensity setting for your miner, it should get rid of the artifacts, however you will most likely end with a lower hashrate as well.

I think I'd rather keep the extra hashrate, I was just curious about this and was hoping there was some easy fix involving the miners. Undecided

If it's a software issue, your only chance is either updating your drivers, or rolling back your drivers. However, artifacts are usually caused by a hardware issue, typically when the card is overheating. Is the card being properly cooled? My card sometimes does this in video games, and then it refuses to turn back on the next day for a while, or it'll shut itself off and stop working. It only happens in 75+ degree Fahrenheit weather tho Tongue

Meant to say driver issue, but yeah. It's a Gigabyte windforce, stays at 60c or lower. Like I said, it's completely fine in games/stress test software (some of which probably push it harder than mining, for example: Mining vs Kombuster both max the usage at 100% but Kombuster is a consistent 5c higher in temp at the same ambients) so I don't think it's a hardware issue.

Hi guys/girls,

I am experiencing smth similar, running on win 7 x64 (7950) 13.1 drivers. In my case whenever I start mining ( using guiminer scrypt alpha ) the pc becomes non responsive. The mouse will move like 3fps, it still mines though. Current settings are int 20, worksize 256, TC 21712. Temps are fine - 74C on the GPU, 71 and 73 VRM1 and VRM2. I have tried lowering to int to and its a tiny bit better. Any suggestion and wisdom highly appreciated

System specs:

ASrock 970 Ext4
8GB 1333 Single Channel
Sempron X2
750W Seasonic

Not sure what this could be but I don't have the unresponsive problem. Mine works completely fine, and if it wasn't for the artifacts I wouldn't even be able to tell the miner is running. It's just annoying when I'm reading something and I can see the twitching black squares in the corner of my eyes. Try a different miner maybe? I would be trying to fix the unresponsive issue first.

AMD isn't writing drivers with mining in mind so I think it's reasonable we run into issues like this, still hoping for a fix though.
