You can also try the following to workaround the problem if fixing the driver /
setup is not possible:

- Set HKCU\\Software\\Wine\\Direct3D\\MaxVersionGL to 0x10000 (DWORD hex value)
in registry;
- run with Mesa environment
MESA_EXTENSION_OVERRIDE=-GL_ARB_shading_language_100

With GL_ARB_shading_language_100 extension disabled Wine won't ask for GLSL
version string and this should allow to workaround the crash.

>From the Wine point of view, the incorrect GL driver behavior is that it
reports GL_ARB_shading_language_100 extension but then refuses to give a valid
GLSL version string. The driver itself complains in the log that things went
wrong with the string.
