Ok thanks, which driver do you have installed? I guess it's
xserver-xorg-video-sis 1:0.9.1-4?

The latest upstream release is currently in experimental
(xserver-xorg-video-sis 1:0.9.3-1), so it would be good to test it.
However, the changelog is pretty small so there are few chances your
problem gets fixed. At least, once we know the problem occurs with the
latest upstream, we will be able to forward this bug upstream at
bugzilla.freedesktop.org.

Thanks,
Brice
