example of a corrupted menu

Version:           4.6 (using KDE 4.6.3) 
OS:                Linux

When using Intel HD Graphics 3000 (Sandy Bridge), some of the menus were
corrupted (see the attached image). For example the window settings menu,
displayed after Alt+F3 or the right-click menus were corrupted like this.

Enabling or disabling desktop effects does not solve the problem, the only
difference is that with effects enabled the black areas are transparent.

Not sure if it's a driver or KDE problem - I'm using the
xf86-video-intel-2.14.0 driver and 2.6.38 (gentoo-r6) kernel.

Adding "export QT_GRAPHICSSYSTEM=raster" to the .kde4/env/qt-graphicssystem.sh
script solved most of the issues, although not all of them. After changing
style from "oxygen" to "plastique" everything works fine.

Reproducible: Always

Steps to Reproduce:
Remove the QT_GRAPHICSSYSTEM and/or set the style to oxygen again. After
restarting KDE, the menus are corrupted again.

Actual Results:  
corrupted menus :-(

Expected Results:  
not corrupted menus ;-)
