Cubic galaxies!?

[Tosv]

Hello!

I have just bought a new computer with a built-in VIA/Unichrome S3 Graphics component and suddenly all galaxies has a... Well, strange appearence. All other things in Celestia are working beautifully though.

With my old computer (which had an ancient Cirrus logic 5436 Graphic??s card) Celestia was slow but fully functional. With my new computer (and the most recent drivers from the manufacturer) all the Galaxies seems to be made by rectangels.

See these screenshots of our friend M31.

This occurs in both the Basic- and the Multitexture render paths (the only two available for this graphic??s-component). I have uninstalled an reinstalled both the drivers and Celestia itself but the problem seems to remain. Either it didn??t help to install the "Celestia-1.4.0pre-FT1"-package. The problem is there both with the "Original" 1.4.0 pre 6 and the one including the new galaxy code.

Apparently the Borg are re-engineering the universe!

I suspect it's an S3 graphics driver bug.
You should try to locate a more recent version of the drivers
(too often systems are shipped with out-of-date software)
and you should report the problem to the authors.

As a workaround, you might try disabling hardware acceleration entirely.
Then your system will use Microsoft's OpenGL software drivers.
They're rather slow but seem to have few bugs.

Yep, I was also thinking about the Borg, but then I though that it just couldn??t be that bad

Well, updating to the latest S3-drivers (from their website) didn??t solved the problem, but disabling hardware-acceleration did! It??s a little slower but it works! Now I'm just going to write a little letter to the tech-guys at S3 and hopefully they can put together a fix for it

Thanks!

Hehe nice one about the Borg!
