Xorg log

I installed from the openSUSE 12.2 i586 dvd. I then upgraded to openSUSE 12.3 beta using zypper dup. The upgrade was successful. I have to remove the virtualbox guest driver and set grub to use 800x600x24 in order for X to start. Then the system boots and displays the display manager correctly.

When I log into xfce I noticed that some of the applications were rendered incorrectly. They look distorted with misplaced graphics and lines through the application. In some cases it also looks like they are transparent. This happens whether I have compositing enabled or disabled. Booting using 'nomodeset' or changing gtk themes does not correct this problem either.

Applications I can confirm the distortion are xfce4-panel and xfce4-terminal. It does not happen on thunar, leafpad, yast, etc.

Kernel is: 3.7.1-1-default
Xorg Driver is: fbdev (As it talks about unloading vesa and vboxvideo)

Reproducible: Always

Steps to Reproduce:
1. Log in to xfce under virtualbox virtual machine.
Actual Results:  
Software looks garbled and does not render correctly.

Expected Results:  
Look the same as other gtk applications.
