Once again, hi-dpi does not matter for these tests. It is not what they are trying to test and there is no other "hi-dpi" testing going on anyway on these other platforms, and I keep saying bug in macos not JDK for the reasons I wrote in
https://bugs.openjdk.java.net/browse/JDK-8274106 which is tracking the underlying issue and is aware of ALL the tests that fail. I looked at the Robot code and it was getting different answers *from a macos api* depending on  whether it asked for some larger region first.
