Default 195.36.03 and 190.53 + compiz = very big slo

195.36.03 and 190.53, gnome
1) Launch compiz
2) Launch terminal
3) view some info in terminal window (tail -f some log for example), so terminal buffer will have several pages of information
4) leave system for some time
5) press page up/down in gnome terminal window - it will take 0.5-1 seconds to navigate !!!
6) collapse window to the task bar and reopen it again
7) scrolling performance will be ok again

gfx card: NVS-140M (Lenovo Thinkpad R61)

also in step 7 there will be noticeable delay on reopening window.

'top' & see what's taking excessive cpu time

check the terminal scrollback buffer setting

check the compiz plugins in the compiz settings manager(ccsm) and uncheck any your system isn't liking or unneeded.

glxinfo | grep 'direct rendering:' ... should be yes

Try other terminal emulators.

There is no excessive cpu usage.
direct rendering in enabled.

Also on 185.xx it was all OK.
It seems that it's something wrong with nvidia driver gfx card memory management.

I can confirm this with NVS 140m (Thinkpad T61) on Ubuntu 9.10 (gnome) with 195.36.03.
Scrolling and tab switching get slower over time in all applications. Sometimes minimizing an application reverts the state.
