The fix for 8274296 added uiScale=1 to some of the tests to fix the problem of incorrect pixel color capture by the robot.
In both cases uiScale=1 or uiScale=2 the same call should be made to the macOS. But if uiScale=1 is set we just read one pixel on the screen, but if uiScale=2 is set we prepare the data in some clumsy way(at the end we should also read just one pixel).
Since uiScale=1 affects the testcase execution means that we probably have some bugs in the coordinate/size calculation of the area.

This is a request to update the https://github.com/openjdk/jdk/pull/5687/files
and move all tests to the problem list.
