Anyone other fixes available yet? I also get screen corruption on other
desktop environments (xfce mainly), but it took a while of heavy usage
on them. It seems to favor corrupting HUD in Precise.

I experience this problem in Oneiric:

problem is gone.
System info shows memory size 741MB. I uncovered the PC and it has

So, running Ubuntu with a lower swap size might help until there is a final
solution for this?

Rui:
Can you reproduce this if you immediately disable swap after you finish booting
(i.e.
sudo swapoff -a
)
Also, how much memory do you have in the machine?

I'm experiencing this problem since I upgraded from 11.04 to 11.10.
I thought it had been a bad upgrade and I then did a fresh install and the
problem remains.
I've also experienced this on both Kde and Gnome sessions.
Sessions without acceleration like Ubuntu 2D are not affected.

so yeah, it's not *exactly* the same hardware as per the bug report but
it is exactly the same symptom and probably similar enough causes... For

zemerica:
OK that confirms the other poster's comments. What is the output of
/sbin/lspci -nn | grep VGA
on that machine and roughly how many minutes did it take before the corruption
appeared?
