I have red rapidly this bug and it seems to bee the same , wee observe with Suse
with some difference it was more important with kde , but now I observe the same with gnome and kde ,
it was solved with the driver
260.19.44 for suse 11.4 and kde 4.6
(my graphic cards is 7300 Gs)
The last trial I did was with 290.10 was perfect with gnome abd kde
