Hi, Tobias.

What do you mean to say ugly? Is it drawn slowly or just a garbage 
appears on the window? If you mean that in time when you resize the 
window the drawing goes correctly, but with a delay (there is a 
background at window border), so it is an expected behavior at this 
moment. In most cases we behave the same way on other platforms. Of 
course this behavior will be improved in the nearest versions. If there 
is a garbage and a picture absolutely incorrectly during window size 
changing, it is necessary to create a new bug on bugs.sun.com. Please 
provide a steps to reproduce(example 
and screenshot.
