In my desktop system Kubuntu 15.10 I have the integrated graphic card
(Intel HD3000) and a discrete graphic card (Nvidia GTX 550). Some days
ago I attached a monitor on the iGPU and enabled it, giving me a triple
head system (two monitors on the Nvidia and one on the Intel). From that
moment, the mouse pointer started to leave a trail when it pass over
something that is animating. I'm using nouveau for the nvidia card. I
tried to upgrade to Kubuntu 16.04, but it gives me the same glitch. It's
not possible to take a screenshot because it will repaint the desktop
prior to take it, so the glitch doesn't appear: I had to take a photo.
