Sorry Sean,

No improvement.

Unfortunately, all of the MASON programs appears to do it.
Here is a copy of
Just so you can see that the code is as you have provided it.
Single step the image does not appear.
Run it appears, if I interrupt the run the image goes away.
If I stop the run it remains on screen.

I never noticed it before as I have not enlarged the display window in any of the MASON provided programs.
In the way that I have been doing with my own program.

Updated details:
Microsoft Windows 10 Pro Version 10.0.14393 Build 14393 X64
                   JAVA jdk1.8.0_121
Eclipse IDE for Java Developers Version: Mars.2 Release (4.5.2)
MASON 19 with a few updated components; GridBounded, GridLines.

I have made sure that everything on this computer has been upgraded to the latest versions.

I am stumped for now.
In the future, I will make sure I keep the frame size matching the display size and pretend it is not there

Thanks for all of your help.

Kind regards,

BTW, with regards to your strange GUI bugs on the window at left in Windows: try running it like this:

java -Dsun.java2d.d3d=false blah.blah.blah.SimEnviroWithUI

(or whatnot)

Any improvement?
