Interestingly I encountered the same issue when working on Xmir rootless support this week. The bug there was that the compositing window manager (now Xmir itself) failed to notice that some sub-windows are flagged as un-viewable in the X server, so those odd little windows need to explicitly not be displayed (unless they are marked as viewable).
