[Wine] SolidWorks and more generally OpenGL CAD apps...

Hello everybody, 

During the past three years, I regularly tested SolidWorks http://appdb.winehq.org/objectManager.php?sClass=version&iId=8983 with Wine. At the beginning, it was just for fun, as it was really far from working.  But now, things has changed : the application installs out of the box and is really close to work. There are some bugs remaining, but the situation is not worse than it was for Autocad a few months ago, for example. But there is is still a big problem with OpenGL http://bugs.winehq.org/show_bug.cgi?id=13195 , that prevents any use. Without this bug, the application will be rated bronze or maybe silver ! 

The OpenGL problem was partially solved from times to time by some patches, but 0.9.47 introduced a big regression. Now OpenGL is definitely broken, with two blocking bugs. The problems are related to Pixelformat choice, child windows management, and offscreen rendering.

I tried to investigate it by myself, but unfortunately I know about nothing of OpenGL and wgl  in wine, so I was just able to file bug reports, and some partial workarounds allowing the application to run, but with big display issues ( see bug 13195).

So my question is : is SolidWorks the only application impacted by these OpenGL issues ? 
I understand that most of the games are using only one OpenGL window so they are not impacted, but there are many other OpenGL apps with multiple windows/viewports. I dig Appdb and bugzilla, and found nothing recent related. So if some other users can report to bugzilla similar problems with different GL apps, it may help to narrow the problem !
