The bug still happens, and I seem to be able to reproduce it reliably when my xorg.conf is set like this (and I run Oneiric in VirtualBox):

==========
Section "Serverflags"
        Option "Pixmap" "24"
EndSection

Section "Screen"
        Identifier "Default Screen"
        Device "VirtualBox graphics card"
        Monitor "Generic Monitor"
        DefaultDepth 24
        DefaultFbBpp 24
        SubSection "Display"
                Depth 24
                FbBpp 24
                Modes "1024x768" "800x600" "640x480"
        EndSubSection
EndSection
==========

I'll take this bug, then.
