Seems the window sizes are incorrect on Linux at least. The left side of the windows are truncated.
Tried with JDK 1.7 and currently jdk 1.8
java version "1.8.0_72"
Java(TM) SE Runtime Environment (build 1.8.0_72-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.72-b15, mixed mode)
Please see screenshots.
