ADDITIONAL SYSTEM INFORMATION :
Windows 10, 64 bit, Version 1909
JDK 14.0.1, 64 bit


A DESCRIPTION OF THE PROBLEM :
This problem could be related to the "resolved" JDK-8196605.
I am using Robot.mouseMove() to move the cursor to a specific location on the screen.
This works when e.g. focusing my IDE's (IntelliJ IDEA) window. When I focus another window and Robot.mouseMove() gets called, the mouse doesn't move at all.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
My attached source code is a minimal example showcasing this behavior.
Just start the script, focus the Task Manager or Terminal and wait until "Moving" gets printed.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The cursor should get moved to position (0, 0).
ACTUAL -
The cursor doesn't get moved at all.

---------- BEGIN SOURCE ----------
import java.awt.Robot;

public class Test {

    public static void main(String[] args) throws Throwable {
        final Robot robot = new Robot();
        Thread.sleep(5000);
        System.out.println("Moving");
        robot.mouseMove(0, 0);
    }

}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Focus another window, which might work (I tested with Microsoft Edge, WhatsApp Desktop and IntelliJ IDEA, which seem to work. I haven't yet found out, which programs work with that).

FREQUENCY : always
