Public bug reported: I am experiencing cpu usage spikes with xorg where everything will lag for about a second. Seems to happen every minute or few.
Other possibly related symptoms: Seeing flickering of the mouse pointer when it's over certain interactive fields or just at the top of my laptop monitor. Experiencing screen tearing in a diagonal line across second monitor When I set up the second monitor, backgrounds fail to display. Changing background fixes. Sometimes the second monitor just starts flicking off and on. Setup: Just upgraded from 16.04 to 16.10 (didn't see any of this on previous version) Using a second monitor connected via display port USB mouse and keyboard connected.
