Public bug reported: When having the gtk2-engines-oxygen theme activated, switching to and from a GTK application frequently will cause the app to use more and more memory, and more and more CPU time. This keeps on going, up to the moment where I need to kill the app because it bogs down the system by going into swapspace.
Both Emacs 23.3.1 and Firefox 13.0 present the same behaviour. I went looking for the cause, and switched themes. After switching this stopped. This made it clear that the problem must lie with the gtk- oxygen theme. Uppon suggestion of from Ruslan over at bugs.kde.org I took the most recent version (1.2.4) for a swing, and this solved the issue. Solution: Could you please bump the version of this package to the most recent one? I saw a similar request already here: https://bugs.launchpad.net/ubuntu/+source/oxygen-gtk3/+bug/991891 , but I really want to stress that this makes widespread GTK apps (think firefox) misbehave, and really become useless.
