ADDITIONAL SYSTEM INFORMATION :
Windows 10, OpenJDK 17.0.2

A DESCRIPTION OF THE PROBLEM :
On Windows, the value of Insets is not calculated correctly when changing the default display.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Changing the default display
After, execute command

java --add-exports java.desktop/sun.awt.windows=ALL-UNNAMED --add-opens java.desktop/sun.awt.windows=ALL-UNNAMED -cp bin M

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
- Case 1 - : Correct

Default:\Display0
\Display0
  java.awt.Rectangle[x=0,y=0,width=1920,height=1080]
  java.awt.Insets[top=0,left=78,bottom=0,right=0]
\Display1
  java.awt.Rectangle[x=1920,y=0,width=1920,height=1080]
  java.awt.Insets[top=0,left=0,bottom=0,right=62]
0: java.awt.Insets[top=0,left=78,bottom=0,right=0]
1: java.awt.Insets[top=0,left=0,bottom=0,right=62]

- Case 2 - : Not correct

Default:\Display1
\Display0
  java.awt.Rectangle[x=-1920,y=0,width=1920,height=1080]
  java.awt.Insets[top=0,left=78,bottom=0,right=0]
\Display1
  java.awt.Rectangle[x=0,y=0,width=1920,height=1080]
  java.awt.Insets[top=0,left=78,bottom=0,right=0]
0: java.awt.Insets[top=0,left=78,bottom=0,right=0]
1: java.awt.Insets[top=0,left=78,bottom=0,right=0]

ACTUAL -
Case 2
1: java.awt.Insets[top=0,left=0,bottom=0,right=62]
