I have upgraded drivers installed (from x-swat), they don't fix the issue. The 
latest drivers require a kernel upgrade too for which I currently don't have 
time - I'll wait for Karmic at the end of the month.

However, I did get my hands on the PC that suffers the same/similar performance 
problems. Find attached the lspci output. Here I also tried to disable 
compositing, with little to no effect.

I also tried the open source nv driver ("nv" instead of "nvidia") and this 
indeed fixed it - pcbnew is reasonably fast again.

However, I do think that this problem needs to be addressed by either KiCad or 
wxWidgets, because disabling Compositing won't really be an option in the 
future for many people. Plus the problem can't be fixed e.g. on my Intel-based 
system. Plus almost none of the other applications I use suffer from these
