The problem is in poor BlackBerry graphical algorithms - they are really rudimentary, as I found out the hard way.
I have a feeling that ZoomScreen uses the same poor algorithms as drawTexturedPath (why wouldn't it?), which I know for sure to be real bad. For example, when you zoom out of a checkerboard pattern with such small squares that you already see it as a uniform gray, BlackBerry starts showing huge squares or bands of black and white instead of just staying gray.
If you search the forums for drawTexturedPath you should be able to find my post reporting this...
