Hi, still see it on ubuntu 13.04 VMs run from kvm (in this case the host
OS is debian/squeeze), including Mint15-Cinnamon.

Interestingly gnome-terminal is corrupted, but xterm and rxvt are not.
pop-up alpha channel overlays which want to 1/2 shade the screen dark
are also corrupted.

Tested with 'kvm -vga std' and indeed that works-around the issue, but
for me (on a fast 6core with plenty of RAM) running Squeeze the VM is
then very slow to render, to the point where it is no longer usable for
anything other than debugging. Using Precise as a host makes '-vga std'
work ok though (even when using kvm via tunnelled X).

'-vga qxl' on Precise just drops me to the qemu text box terminal,
doesn't boot. the qxl xserver xorg video driver package is installed on
the VM client, so I'm not sure what's going wrong there. But at least
the '-vga std' + 12.04 host combo is a good one.


thanks,
Hamish
