>> @andreas-heger Welcome to the `jfx` project. At a quick glance, the fix looks promising. Have you tested this on Windows with Hi-DPI to make sure there is no impact? Would you be able add an automated test case that fails (only on Mac retina) without the fix and passes (on all platforms) with your fix? Hi-DPI fixes are often tricky to test in an automated test, so if not, we can use the existing manual test.

The test will be passed if the calculated average does not differ from the excepted average color by a certain tolerance value. I'm not sure if I will manage to do this... but I will give it a try.
@andreas-heger are you able to come up with an automated test for this bug?
