FULL PRODUCT VERSION :
java version "1.8.0_162"
Java(TM) SE Runtime Environment (build 1.8.0_162-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.162-b12, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 10.0.16299.214]

EXTRA RELEVANT SYSTEM CONFIGURATION :
Lenovo w540 laptop with two graphics adapters: Intel (the default one) and NVidia. All software updates and latest drivers are installed.

A DESCRIPTION OF THE PROBLEM :
The code snippet below demonstrates that java.awt.Robot does not move mouse pointer to the specified position.

Code:
public static void main(String[] args) throws Exception {
  Robot robot = new Robot();
  for(int x = 0; x < 1920; x += 192)
  {
    robot.mouseMove(x, 0);
    robot.delay(1_000);
    final Point location = MouseInfo.getPointerInfo().getLocation();
    System.out.println("Expected: " + x + "\t\tReal:" + location.getX());
  }
}

Output:
Expected: 0		Real:0.0
Expected: 192		Real:239.0
Expected: 384		Real:421.0
Expected: 576		Real:614.0
Expected: 768		Real:807.0
Expected: 960		Real:998.0
Expected: 1152		Real:1191.0
Expected: 1344		Real:1382.0
Expected: 1536		Real:1574.0
Expected: 1728		Real:1767.0

I found similar report https://bugs.openjdk.java.net/browse/JDK-8190898 which is closed as "Incomplete".  The problem is perfectly reproducible in my environment and I'm ready to provide all necessary further details about my hardware configuration (Lenovo Thinkpad laptop).

I found that calling in loop robot.mouseMove(x, 0) finally moves mouse pointer in 3-5 attempts.


REPRODUCIBILITY :
This bug can be reproduced always.
