I'm having a Scala (Java) app open a
javax.swing.JFrame and put it to full screen; the physical display is a 3.5" touch screen on the GPIO. I just noticed that when I click on parts of my UI where there are no buttons, the mouse/touch events seem to be passed through to other windows "below" my full screen window. So a user can accidentally start dragging a terminal window, bringing it to the front, etc.
Is this a known issue? Is there a work-around to prevent this from happening. Needless to say, this doesn't happen on a desktop computer (Debian).
Perhaps I can "move to a new workspace" or something to ensure that "nothing" is below my full screen window?
