Looks like it is the pixel format indeed. I've added a quick and dirty hack in
dlls/winex11.drv/opengl.c, that includes only the format with id 0x77 in the
list, that has an alpha channel with my video card:

Output from glxinfo -t:

Without the patch the format 0x75 is used (no alpha channel => white screen).
With that screen effect works. I just don't know how to make a usable patch out
of it, so that the format with alpha channel is preferred... ;)
