Bug Description

I'm noticing some random screen flickering since 16.10 upgrade. Something like every 10 minutes, mainly on the secondary monitor (hdmi connected), but sometimes on the laptop display too.

Not sure if it's related, but when using LibreOffice Impress to display presentations on the secondary display the problem worsens, but it's only flickering in parts of the display, not all.

This affects me too.

Wasn't an issue in Xubuntu 16.04 with three monitors plugged in to my desktop machine. However, after upgrading to 16.10 I am now getting occasional screen flickering that worsens in frequency over time. This seems to occur when the mouse pointer travels across monitors, with the worse flickering occurring on the primary monitor. Strangely, suspending to RAM and resuming the machine seems to *reset* the issue but not fix it.

There are several other visual glitches affecting Libreoffice too.

Let me know if you need me to gather any information about my machine.
