wine users - Jul 2008 - ABA's Brain Explorer and the OpenGL offset problem

I've seen reports on appdb of SketchUp having the same problems. Have 
these been resolved yet? I think this has been called the "OpenGL 
offset problem".

Might be related to DRI in xorg.conf files?

This bug is maybe related with bug 13185, which affects SolidWorks.
http://appdb.winehq.org/objectManager.php?sClass=version&iId=8983
 It is a regression of the long-time known  OpenGL child windows bug. 

As far as i understand it, the issue is related to a bad management of multiples
drawables or windows, especially with line redrawing in CAD applications.

I'm really surprised that no other 3D CAD apps are impacted. Maybe lack of
testing ?
