Running Kubuntu 11.04 Natty Beta1

Sometimes when changing plasma theme, the panel theme refuses to update
it self without a logout. Transparency effect on taskbar does not always
work after changing a theme.

The blur effect does not work at all although it is checked and KDE does
not give an incompatibility popup for this effect.

All these effects worked fine in Kubuntu 10.10 with KDE SC 4.6.1 PPA
version. Desktop composition overall is less snappy in natty.

This bug is reproduced on the following graphic cards.
Intel Corporation Mobile 945GME Express Integrated Graphics Controller
Intel Corporation Mobile 4500GMA Express Integrated Graphics Controller

Notice the "Direct rendering: no" If I disable the direct rendering
option in Kubuntu 10.10 Maverick systemsettings, it reproduces the exact
behaviour I am experiencing on Natty.
