Ok, I think I got it. Looking at /boot/config.txt I saw:
# NOOBS Auto-generated Settings:
I commented out all the overscan_* and set disable_overscan=0. Launching
startx, I see that the graphics covers the full screen (some pixels are
clipped out, so X11 would really require some overscan, even though a
smaller amount). But now JavaFX covers the full screen. Also for JavaFX
there are some pixels clipped out. This is not a problem for me: I think
that it's up to the JavaFX application to correct for overscan, by simply
putting some space around the true contents.
So, the thing now is fine for me. But I think that there is a real bug:
JavaFX is not correctly computing the screen area when there's that
overscan settings. It's probably a low priority one - maybe it would just
make sense to warn people about it.
The mouse is ok, it was probably a connection fault. The keyboard
navigation of buttons is still not working - still investigating.
