Since the behavior exhibits itself in gnome classic without effects, and since turning -vga std on works around the issue, it is sounding unlikely to be mesa, and more likely to be the video driver itself (-cirrus, or potentially the kernel).
Does booting the quantal kernel in the raring vm (without using the -vga std workaround) also work around the problem?
