Comment 23 for bug 357901

I have the same issue here with three monitors, all separate X screens with xinerama on and twinview off. I have two nvidia 7300 GTs in this box. The problem occurs quite often, several times an hour and may disappear immediately or hang around for a minute or two, I can't seem to work out what makes it sort itself. The SWCursor fix causes severe trails that make one of the monitors unusable.
