A DESCRIPTION OF THE PROBLEM :
When switching from a lower resolution monitor to a higher resolution one (4k) the file menus become disjointed and unusable. This previous ticket addresses the same issue but it seems to have regressed:

https://bugs.java.com/bugdatabase/view_bug.do?bug_id=JDK-8169777

REGRESSION : Last worked in version 8

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
When using a program with a JavaFX file menu, open the file menu and then drag the program to another display with 4k resolution

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The file menu dropdown remains connected to the menu bar so that it can be used
ACTUAL -
The file menu dropdown is displaced rendering it unusable

CUSTOMER SUBMITTED WORKAROUND :
Launching the program on a monitor with 4k resolution to begin with (setting that display as the primary display in Windows, for example) will cause the issue to be temporarily resolved

FREQUENCY : often
