Screenshot comparing llvmpipe and r300g

The DirectX9 demo "rthdribl" isn't rendering correctly with r300g. 

This is partly a regression from the glsl2 merge, but probably not a problem in the GLSL compiler since llvmpipe seems to handle the demo. Rendering wasn't 100% prior to the glsl2 merge either.

The "glare" filter causes the screen to be drawn mostly white, so be sure to turn it off: 
Options → Glare → Glare Type → Disable

Version 1.2 of the demo can be downloaded here:
http://www.daionet.gr.jp/~masa/rthdribl/

You'll also need mfc42.dll:

Is this still an issue with current mesa git?

No change.
Comment 4 Tom Stellard 2010-11-21 21:53:53 UTC 
Can you try this again with the latest git master?
Comment 5 Sven Arvidsson 2010-11-23 07:18:17 UTC 
No change here.
Comment 6 Marek Olšák 2010-12-17 05:20:40 UTC 
It seems to work very well without the Glare effect here.
Comment 7 Sven Arvidsson 2010-12-18 14:16:17 UTC 
Yes, it looks like it's only the glare effect that's broken now. I guess I forgot to update the bug.

Unfortunately it looks like llvmpipe isn't rendering the demo correctly any longer. It was a good comparison otherwise.
Comment 8 Marek Olšák 2011-06-08 17:35:13 UTC 
It works well with float textures and doesn't work without them, so I am closing this bug. It's kinda blocky though, but that's because R300 cannot filter float textures.
