Descriptive Problem Summary:
Using opaque atoms could sometimes cause screen objects not to appear, if the screen object was on a tile hidden by the effects of opacity.
Numbered Steps to Reproduce Problem:
(Exact method to reproduce this issue is uncertain, but varies based on whether screen objects extend past the regular map borders, and if pixel offsets are in use. A demo project was provided.)
Screen objects on the hidden (blacked-out) tiles should still appear.
Screen objects sometimes did not appear when on a hidden tile.
