           Summary: Gallium R300g - celestia's stars are missing with
                    "OpenGL vertex program" rendering path
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/Radeon
        AssignedTo: dri-devel@lists.sourceforge.net
        ReportedBy: rankincj@googlemail.com


I am running celestia with a Radeon 9550 (RV350) and Gallium from git. When I
cycle through all celestia's different rendering path options with Ctrl-V, all
the stars disappear when I reach "OpenGL vertex program".

The stars are also missing with the "OpenGL 2.0" rendering path, as are all the
textures for planet Earth.

No stars visible behind the Earth from this angle.

With the "OpenGL vertex program" and "OpenGL 2.0" rendering paths, there are no
stars visible behind the Earth. Switch to "Basic" or "Multitexture" under
r300g, or "OpenGL vertex program" under r300c, and the stars reappear.

Rotate our viewpoint, and the stars come out.

Rotate our viewpoint around the Earth, and the stars appear again. But they're
using a lot more pixels per star than I would have otherwise expected.

And now the stars are large and square

Err, so how long is it since you looked at the night sky ;-) ?

Ooops, that doesn't look right.

Nevertheless, celestia renders stars correctly here (RV530), the stars are of
the same size in all rendering modes and they really look like "stars" (wait,
looking at sky... yep they do). Nothing to fix here. :(

RV350 here: AGP with PCI ids 01:00.0 0300: 1002:4153. The problem here is that
the RV530 fix has made the RV350 case even worse.

Both softpipe and llvmpipe render the stars correctly here, it appears to be an
RV350 issue.

To confirm: reverting the single line of commit
0ad541a684ca55e883a0bcde9ab8b5d73806269a restores the original behaviour.

Chris/Marek, which star style have you selected in the celestia Options menu?
With 'Points' I get something like Chris' last screenshot (which is kind of
expected I think, as r300g doesn't support smooth points properly yet), the
other styles look much better on my RV350.

I don't have "Points" in the Options menu. It's Celestia 1.6.0 here.

It's Options -> Star Style -> Fuzzy Points / Points / Scaled Discs.

Yes, my star style is "Points". The other two styles render correctly.

Fixed as of the commit 084580fa43320b1a0878b572c6804aa5a40b2f9d.

There is no Star Style option in the kde frontend. I've had to use the gnome
frontend instead.
