John,
This appears to be a Catalyst (fglrx) driver bug. Please try removing
the driver and using radeon instead.
Alternatively you can try reverting back to the rendering method used in Ubuntu
12.04:
CCSM > OpenGL >
framebuffer_object = OFF
vertex_buffer_object = OFF
always_swap_buffers = OFF

Title:
[fglrx] Unity flickering on window updates
Status in “fglrx-installer” package in Ubuntu:

Status in “unity” package in Ubuntu:
Incomplete
Bug description:
[Description]
When hovering over icons on unity or using an application which does a lot of
re-drawing there is significant flickering and graphic corruption. This only
happens in 12.10 downgrading to 12.04 fixes the issue.
[Work Around]
unity --replace sometimes fixes the issue (ie you have to do it two or three
times, but eventually it does fix it and the issues doesn't re-appear for that
desktop session).
[Easiest way to force the flicker]
I have found the easiest way to force a flicker is to drag a window frame to
the right hand side of the screen so the yellow bounding box appears on the
right half of the screen, when this happens a lot of flickering occurs.
[Possibly duplicates]
I've found a few bugs with similar problems, however these are for different
versions so wasn't sure if they were duplicates or not bug #963093 ; bug
