So... I have a pretty huge problem with compiz. Every part of the desktop that does not get repainted slowly starts to get all blurry and unusable. If i make the area repaint itself (clicking, doing anything with it), it comes back to normal.
For now, the only solution i found is to force redraw that entire screen (CCSM > Solutions > Force full screen redraws). While this fixes the problem, it causes a MASSIVE CPU and GPU increase (at least according to the help).
I need to use Compiz for eyecandy reasons and Nvidia drivers for gaming (and the fact that Nouveau sucks)
I am using a GTX 970, but this problem also happened on Kubuntu with a GT 630... I have 2 screens.
