Screenshot of hidden child windows.

Poser 7.0 is a 3D model manipulation and rendering program.  It has a main
background window and several child windows, including a 3D viewport using
openGL.  It runs quite well in a virtual windows desktop in version 0.9.55.  In
versions after that, when the 3D window is manipulated, the child windows all
disappear behind the main window, as shown in the attached shot.  Resizing the
main window will allow one to bring the child windows to the foreground, but it
happens after EVERY manipulation of the viewport.  It only happened very rarely
under 0.9.55.

This doesn't occur when running on the KDE desktop using the window Manager;
however, in this mode moving the window causes the cursor to flash between the
normal pointer and the cross shapped move window icon, and the mouse buttons
and keyboard to become unresponsive for between 20 seconds and one hour-this
did occur prior to version 0.9.55(I suppose I should report this one whilst I'm
here). Eventually the flashing stops and the window can then be moved.

I'm running openSUSE 10.3 with KDE 3.59 and the nVidia proprietary video
drivers.
