Log of: WINEDEBUG=+wgl,+opengl wine ./glWin.exe

OpenGL on an ATI Radeon HD6970 with the fglrx driver release 11.12 (8.920)
fails when the rendering context is created in a child window. The example
program here demonstrates the issue: http://www.songho.ca/opengl/gl_mvc.html,

When I run that glWin.exe with WINEDEBUG=+wgl,+opengl, the log shows that
rendering is going on and wine indeed gets the calls and does not return
errors, but on screen the window is full of garbage (old framebuffer contents).

It's probably a driver bug, but maybe there's some workaround...

AMD driver release 11.10 had the same problem. I did not try older versions.

This is probably not a duplicate of bug 16806, because the rendering works just
fine with an NVidia graphics adapter and their closed-source drivers, using the
same wine version.
