As per the title really.
Every single day my mouse cursor goes corrupt at some point and the only way to fix it is to restart the computer. I have just about had enough and am very tempted just to sell my 290X and buy a 970 for an easy life.
I have had this happen as well when running an ATi / AMD card, though thankfully it has been a rare occurrence. I can't recall whether it has happened or not when using an nVidia card.
I've had that happen before, probably back when i had 7970s.
Didn't even know it was a fault (with AMD, thought it was something else) just lived with it till i restarted computer or whatever
