What about Xig's (E&S's) Glaze? ftp://ftp.xig.com/pub/Summit/extras/ I see transparency bugs on r200 with "Presets: 7" and _without_ "Back Faced Culling" (State:). More visible with "Ball" Object (New Object).

With software mesa it works just fine. Same (?) with texcyl: "Reflect" show an empty/black window. LIBGL_ALWAYS_INDIRECT fix it. > Any ideas what could be going on, the mesa blendeq demo works correctly > interstingly. But redraw is missing when the window would be drag around? LIBGL_ALWAYS_INDIRECT fix this, too.
