I think I identified the culprit, at least for now. I changed the
precision for some of the scaling calculation from the client to the
server window(s) (see patch below), and that fixes the problem for me.
It's committed and should be in the dailybuild tomorrow.
However, there could still be problems if people use very small windows
on the client side. So don't be tempted to use a 1x1 window on the
client side because you don't need it anyway, right now that will give
pretty unexpected results.
Hope it helps
Dirk
