After the screen saver came on, I cannot now reproduce the problem. I'm starting to suspect that the problem is either to do with the drivers for the ATI card I have or with OpenGL as the problem was originally observed after the machine was hung by the screen saver and required a hard reboot.
I'll do some further testing and will enable debugging symbols if I find a way to reproduce the problem. Appologies for the inconvenience till then.
