ADDITIONAL SYSTEM INFORMATION :
RHEL 8.10 using Gnome 3 paired with openJDK/JFX 17.0.14

A DESCRIPTION OF THE PROBLEM :
primaryStage.setX(x) and primaryStage.setY(y) do not result in the window being placed at the specified location when the result of applying the XY would result in the window spanning 2 monitors. When this case is encountered, the window is forced to display on one monitor of the other, neither of which match the coordinates that are applied.

REGRESSION : Last worked in version 8

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Assuming you have two monitors that are setup up right next to each other with a resolution of 1920x1200. Update via code a window (window dimensions 500x300) X,Y coordinate to be be at X=1900 and y=300.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The origin of the window is displayed at (1900,300), which displays the window across the windows.
ACTUAL -
Window is forced completely to one monitor.
