We are replacing some of our older computers w/ the newer 5K Retina iMacs and have noticed that some of our older objects/buttons no longer display properly. This is also true for newer 3rd party non-Apple Hi-Def displays. The objects appear black instead of in their original form. When the same object is displayed on an older monitor, the objects display correctly.
This is what the object should look like:
Any thoughts on what could be causing these objects to display black on newer displays?
