Description hxr10011 2011-05-07 12:55:40 UTC 
Badly rendered window title-bar and desktop menu in KDE Plasma 4.6

Description of problem:

Using a new Thinkpad T420 with the Intel HD 3000 graphics card, 1600x900
display:

Pop-menus, the system's application menu, and window title bars are rendered
badly, both with and without desktop effects enabled. This was confirmed using
a full install as well as with the Fedora 15 Beta KDE Live CD.

With desktop effects turned off, the background of mis-rendered items comes out
partially black. With effects turned on, they usually come out partially or
entirely transparent. Both cases make menu items very difficult to read.

Version-Release number of selected component (if applicable):

The latest KDE and intel driver as of filing this bug:
xorg-x11-drv-intel-2.14.0-6.fc15.x86_64
qt-4.7.2-8
kdelibs-4.6.2-4

How reproducible:

Right click on desktop to open desktop menu

Steps to Reproduce:
1. Log into KDE 4.6 Plasma
2. right click on the desktop to get menu
3. view menu with badly rendered background

Actual results:
