runiter,
This code is before my time, but I've never seen a way to get the best graphic configuration with having the frame display, I think it's because most windowing system can't query the hardware capabilities without reserving actual screen real estate. Certainly plenty of c++ coded applications put up a tiny blank window before resizing to the desired resolution.

The only other option I can think of to use if you really want to get rid of the flashing square is
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gd = ge.getDefaultScreenDevice();
GraphicsConfiguration[] gcs =  gd.getConfigurations();

Then pick the configuration that matches what you want

But of course knowing what the user wants requires a pile of display selection dialog code etc.
Then you also want to ask full screen or not, pixel depth, AA, anisotropic, stereo, possibly stencil bits, z bits etc.

I've got some code that does some of teh screen resoltion detection and dialog options here:

But it's only about half way to what you'd need.
