[Paraview] Paraview super slow in KDE?

[David Doria]

This weekend I switched from gnome to KDE (Ubuntu 11.10). The first
thing I noticed this morning is that Paraview is SUPER slow. When I
open a vtp file, even before I click "apply", it spends 10 seconds of
cpu at 100%. If I move the scroll bar in the "information" panel,
again before "apply" has even been clicked, it spends 10 seconds with
the cpu at 100%.

Any thoughts on what could cause this? I built git master yesterday.

Thanks,

David
