Help test the behavior of a multi-screen setup with both Mac and Windows

[Thiago Milczarek Sayão]

Hi,

Could anyone with a multi-screen setup on Mac and/or Windows please share
the results of the two buttons on this sample app? Your feedback would be
greatly appreciated!

On Ubuntu 24.04 the first button moves the Stage to the end of the first
screen (bit weird).
The second work as expected, it gets moved to the start of the center of
the last screen.

Thanks!
