I'm not certain, but it sounds like a problem I have seen on MacOS.

In my case, I was unable to see the menu bar and the status bar at the same 
time. In each of these cases, the plot was shifted vertically.

I was able to fix this by uninstalling fltk-aqua-1.1.10. The package for 
fltk-aqua-shlibs-1.1.10 remains installed.
