Ernest -- Try changing the StandardSystemView of the window in question
to a ColorSystemView. This version caches an image of the window at
display depth rather than assuming that a depth-one image will do. The
StandardSystemView is probably called out in an openOn: method. You will
probably have to change several. 

Another approach might be to define one or more "quick color" keys that
add color to aid in some specific debugging task. You could then let the
color revert to normal when you didn't need it. This would be kinda like
clicking on a left parenthesis to find the matching right. Good luck. --
