A DESCRIPTION OF THE PROBLEM :
Assume a Windows system with two screens.
Screen 1 has set a scaling of 100%, screen 2 has set a scaling of 200%.
If screen 1 is set as the primary screen (in the Windows display settings), getBestCursorSize() returns
java.awt.Dimension[width=64,height=64]

If screen 2 is set as the secondary screen, getBestCursorSize() returns 32x32.
java.awt.Dimension[width=32,height=32]

As no screen resolution has changed, it is surprising that the result of getBestCursorSize changes.

This problem is closely related to JDK-8240568. If the primary screen has the greater scaling, the cursor is normal/double sized if the primary screen has the greater scaling, and is half/normal sized if the primary screen has the lesser scaling).


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Set the respective Windows settings and run the submitted test program.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
java.awt.Dimension[width=64,height=64] in both cases, to support the greatest scaling value well.
ACTUAL -
java.awt.Dimension[width=32,height=32] in the case where the low-scaled screen is set as the primary one, java.awt.Dimension[width=64,height=64] otherwise.
