--- Comment #4 from Roderick Colenbrander thunderbird2k@gmail.com 2010-04-14 07:13:13 --- The bug goes away if you disable GL_ARB_map_buffer_range by adding a '//' in dlls/wined3d/directx.c: // {"GL_ARB_map_buffer_range", ARB_MAP_BUFFER_RANGE, 0 },
It is too early to say whether it is a Wine bug or a driver bug.
