So, after I fixed the two screen problem I was having with my Ubuntu setup, I started getting an odd flickering.
This flickering didn’t affect the whole screen, rather it seemed to be something to do with window repainting, and it became even worse after I updated to 14.04.
I run a slightly non-traditional configuration, in that I run Gnome2 fallback rather than Gnome3 or Unity, therefore this probably won’t effect a lot of people, and is probably why it persists.
After a bit of digging, I discovered that this is actually a compiz issue. Here’s a summary of the fix:
Fixing the flicker
- Install the compiz settings manager:
apt-get install compizconfig-settings-manager
- Scroll down to “Workarounds” in the “Utility” section:
- Select “Force full screen redraws (buffer swap) on repaint”:
Once this is done, your windows should repaint as normal.
