The code which you tried to revert if not correct. The previous change 
was done as a fix for HiDPI support. Lots of our code depends from the 
XWindow.scaleUp/scaleDown/getScale which ware implemented on top of 
graphicsConfig. If it was not updated then this is a serious bug.

I filed a separate bug to fix Toolkit.getScreenSize() on unix.
