I believe setPreferredSize in the constructor is still needed, right?
I guess it will be better to use PREFERRED_WIDTH/HEIGHT+x instead of hardcoding the value..

It seems there is a lag when L&F changed from Java to GTK and the frame takes some time (approx 5 sec in my testing) to set its size to greater dimension.
Also, when moved back from GTK to Java, the height is less compared to what it started off initially in Java L&F and part of the JInternalFrame frame0 is cut off...Are you seeing the same?
