I suspect a little misunderstanding here. I'm using Squeak VM 3.9-8 and 
the final 3.9 image. Under Windows it just works fine, under Linux 
however, the redraw performance of morphic windows is
very slow. You can imagine how slow it is, if you install Windows 
(without any extra drivers), set a higher resolution and try to move any 
window of any application. You will get the same symptom.
