I believe this bug is also the source of problems for Terragen2. It is a 3D
landscape generation tool that has some OpenGL windows within the interface. It
seems to function just fine except for the GUI widgets disappearing.

I'm on a Gentoo system, Nvidia GLX, last tested using Wine-0.9.28

Terragen2 can be freely downloaded to test against Wine if you would like:
