Description of problem: All pull-down menus in KDE 4.6 are distorted and unreadable. (the rest of the window treatments appear OK) This is only a problem with Intel Sandy Bridge integrated graphics.
The machine in question is a relatively new Dell Latitude E6420
Version-Release number of selected component (if applicable): 2.14.0-4
How reproducible: Always
Steps to Reproduce:
1. Boot into x86_64 KDE Live CD
2. Open Konsole or any other KDE program
3. Pull down the file or edit (or other) menu
Actual results: Menu items are unreadable and their backgrounds are completely distored.
Expected results: normal menus.
Additional info: This bug was also encountered by the Ubuntu team (see: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/750964 ) and there appears to be a patch contributed that reportedly fixes the issue.
Intel also released 2.15.0 last week, but I haven't had a chance to patch that into the SRPM to see if it fixes it also.
I haven't tried the 32 bit live CD image yet, so I'm not sure if this bug is architecture specific or not. If you want, I will do so.
Since this was a live image, I didn't even check yum update yet. There's an update to this driver. I'll test it shortly.

Installed the x86_64 version of the F15 beta to disk, yum updated the relevant libdrm, mesa-* and xorg-* packages. Rebooted, and problem still exists.
Tried the work-around suggested in the Ubuntu bug in addition to installing 2.14.0-5 and that does mitigate the problem. Though you can see the extra repaint needed to keep the menu from corrupting.
Next step is for me to try 2.15.0
Updated to 2.15.0 and removed the xorg.conf, and the problem disappeared completely, with no obvious repaint or other performance issues.
Fixed SRPM: http://www.deepgroove.org/rpm/xorg-x11-drv-intel-2.15.0-1.fc15.src.rpm
p.s.: I didn't correctly update %changelog in the spec for that srpm, sorry!
