Why hiDPI does not matter for the tests like these PaintNativeOnUpdate/BackgroundIsNotUpdated/TranslucentJAppletTest? All of them may have different bihaviour in low and hi modes. > there is no other "hi-dpi" testing going on anyway on these other platforms I run the tests in this mode all the time. > 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. It is just impossible that CGWindowListCreateImage which we use to catch the pixels returns different results, since we call it using the same coordinates, it does not affect by the uiScale option. The bug in some other place/methods. We ever calculate the wrong bounds/size of the image or incorrectly store it. ------------- PR: https://git.openjdk.java.net/jdk/pull/5766
