Linux Window Decoration not being applied

On starting the Graal client, the window decorator is not properly applying the window decoration until the window is resized.

Why are you running Linux with a Mac Dock emulator on a Mac machine?

I have never encountered this problem on either Fedora or Ubuntu (the two I have tried Graal one) though I will admit there were some problems installing it.
