Square cursor mouse on ATI videocards with multiple displays

On multiple displays with ATI cards (4xxx and 5xxx series) you may find a square cursor on your first screen, then you move the mouse to another screen and the square cursor goes back to normal.

Resolution:
1) Open magnifier (win + u) and leave the magnifier opened at 100%. That's a temporary fix.
2) Change the drivers of your videocard. The bug reappeared again in the ATI catalyst drivers version 10.5 Rolling back to version 10.4 took care of the issue for me.
Luckily there is not a whole difference performancewise from version 10.2 up to 10.4 at least.

I don't know what exactly causes this bug, it's not only a bug on gigabyte cards, I also encountered this bug on ASUS motherboards, perhaps it's a programming error, but this bug is really annoying.
