[Bug 356438] [NEW] X becomes sluggish after only 4 open windows

[cfraz89 at gmail.com]

Public bug reported:

Running Kubuntu Jaunty devel fully updated on an EeePC 1000H (Atom 1.6ghz, Intel 945GME). Using EXA for acceleration. However when kwin has compositing enabled, X becomes less and less responsive as more windows as opened.
Once 4-5 windows are open, it has become extremely sluggish to the point where you can type and watch the letters follow after a few seconds. 
This does not occur with compiz, or with kwin without compositing. Suspecting a texture memory leak of sorts.

I have tried updating intel drivers from xorg-edgers, and enabling UXA
in xorg.conf, however this just makes the framerate 10x worse.
