Since upgrading from karmic desktop to lucid I have started to experience display corruption. All my windows start to have dotted lines drawn across them, and also the desktop. The issue does not occur immediately after starting X, and can sometimes take a long time to occur. However, once it does occur, it gradually starts to affect all windows and the level of corruption starts to increase. It does appear that windows are affected individually, rather than the entire display being affected as one big canvas. See attachment for an example of the corruption in a Firefox window.
The behaviour in this bug is very similar to that in bug #546827. However, that issue has now been fixed for the original reporter but is not fixed with my set up.
I am using an nvidia GeForce 7600 GS, running the nvidia-glx-185 driver. It's a multi-monitor setup using xinerama.
