Screen flickering and tearing

[Peter Strapp]

Hi all,

I have come across what appears to be quite a nasty little bug. After a
while the right hand side of the display begins to tear and flicker to
the right of objects. I have only noticed this in recent FSO builds
using 2.6.28 kernels.

The only other time I've seen this kind of tearing effect was when
rotating the screen using xrandr before all the kinks were sorted out (6
months ago).

that is how how it appears)

you can just make out the jittering next to the house icon)

Has anyone else seen this before as I'd really like to rule out a
hardware problem?

Peter.
