The Xorg build in Karmic seems to have the composite extension turned on by default which caused horrible tearing on my build. This can be disabled by adding the following to your xorg.conf file:
Code:
Section "Extensions"
Option "Composite" "Disable"
EndSection
This fixed the problem with xbmc but caused some ugly problems with gdm which caused the display to not refresh properly when the xsplash animations played.
