I also have this bug using 980gtx in SLI with Loki(0.4). There are white squares/dots in each corner and when I switch to multitask view, the background behind each desktop window is multicolor/static grid instead of black.

I have the same issue, dots in the corners and static background. It starts after a suspend, i's gone after a reboot.
It only seems to happen when I use a proprietary NVIDEA driver, not when I use the X.Org X server / Nouveau driver.

I'm still experiencing this issue. The dots go away when I change the resolution but the static background is still there.
