GIMP slowdown with 195.x.x and 256.x.x drivers
I have performance regression in GIMP after upgrading to 195.x.x drivers. The same with upgrade to 256.x.x. Pen trail lags against real pen position up to 10 seconds. 'top' shows that 60-65% of CPU is occupied by X and all other occupied by GIMP while drawing.
There is no kind of such problem with 173.14.25 and earlier drivers. However there are some other problems with video playback, user switching and so on - so I have two bad choices: no video and reboot for user switching or no GIMP. Not good.
Is it any workaround to issue with 195/256 drivers and my configuration?
