--- Comment #3 from Rafał Mużyło galtgendo@o2.pl 2011-08-02 08:45:58 CDT --- Well, a quite amusing change took place. Mesa 7.11 was released and the glyphs appeared, but so did "Mesa 7.11 implementation error: Unexpected texture format in radeon_update_wrapper()" warnings (from src/mesa/drivers/dri/radeon/radeon_fbo.c). Now, the funny part is that no significant changes seem to have been made in r200 private code - it looks like this was an effect in the shared radeon code.
Not that I did a bisect (cause I didn't), but given the warnings, after looking at the git history, I'd suspect "mesa: Switch generate_mipmaps_compressed() to using TexImage2D to upload." commit.
Now, the question is "is mesa doing something odd or is wine".
GL_INVALID_ENUM warnings are still there, but it seems we've already established, that those are about something regarding GL_ATI_fragment_shader extension, that (according to comments in wine sources) seems unused outside r200.
