Public bug reported:

Binary package hint: nvidia-current

I work using eclipse (gtk), konsole(qt) and keep firefox (gtk), kmail
(qt) apps open in my kubuntu desktop (plasma, no desktop effects).

After a while -- feels like related to the amount of text displayed
(opened eclipse tabs, open konsole tabs, the amount of data in konsole
and eclipse console), not depending on the amount of time used --
everything slows down considerably.

GTK apps gradually slow down first, followed by sudden slow down of qt
apps.

Example of qt slowing down is kmail writing responding to typing with
delay of 0.5 ... 2 seconds (per character typed).

Closing all applications and restarting them fixes the slowdown.

The problem began at 10.10, and persists even when using x-swat latest
nvidia packages. QT raster rendering does not help the problem.

I guess there's not much that can be done, expect I try to monitor the X
resource usage.
