Windows, you can move a window (even if maximized) to another
screen <br>
with Win+Shift+Arrow key. When doing this, a JavaFX stage does
not <br>
resize itself to the new screen if the other screen has a
different <br>
size. You get stuck with an application where the titlebar
looks like it <br>
is in fullscreen, but it does not fill the screen.<br>
<br>
I would suspect there is some kind of rule built into some
JavaFX part <br>
that internally prevents resizing maximized windows? Because I
have only <br>
seen this happen with JavaFX windows so far.<br>
<br>
I can open a ticket for this, but I would have no idea how to
fix this <br>
issue.<br>
