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 ?
