[Bug 607509] [NEW] Distorted text and graphical anomalies

 

Public bug reported:

After booting graphical distortions start to appear. Redrawing the
screen seems to temporarily fix them and they slowly get worse the
longer the machine has been booted.

See screenshot for an example and it can get much worse after 8 hours
use.

This problem only started happening as of 10.04 LTS.

OS: Ubuntu 10.04 LTS

Box is a custom built machine. I will attach my xorg.conf and a
screenshot.
