Description Fabio Pedretti 2015-01-22 18:42:47 UTC 
When running Tales of Monkey Island game with quality >= 7/9 using iXit mesa master branch I get the following error:

r300compiler error: Failed to translate rgb instruction.
r300 FP: Compiler Error:
Failed to translate rgb instruction.
Using a dummy shader instead.
r300: Initial fragment program

If useful I attached the output when running with "RADEON_DEBUG=fp wine MonkeyIsland101.exe > ~/nine-tales-monkey-island.txt 2>&1".

According to axeldavy on the gallium-nine github issue tracker ( https://github.com/iXit/Mesa-3D/issues/64 ) the shader seems fine, it is likely a r300 compiler error.

I have a Radeon RV530.

Possible fix

Can you try this patch?

The patch fixes the error, thanks.

The rendering is also improved but not correct however, while before the patch I got a black screen now I get the attached blurred image.

Running nine with D3D_ALWAYS_SOFTWARE=1 shows a proper render.
Comment 4 Fabio Pedretti 2015-01-23 14:13:46 UTC 
The patch also regresses other games with different corruption types (e.g. sauerbraten becomes in black/white, 0ad has flickering textures).
Comment 5 Tom Stellard 2015-01-27 20:26:35 UTC 
Can you send me before/after dumps of RADEON_DEBUG=fs,vs,ps from one of the regressed games?

I tried it with "RADEON_DEBUG=fp,vp,pstat" since "fs,vs,ps" apparently are not available. I tried running "sauerbraten -lforce" which shows black/white textures.

Note: it looks the output changes between consecutive runs, although there are not many possibilities (an output repeat after some runs). I attach the outputs before and after the patch that should hopefully match to the same game combination.

0ad main menu console output

Here is another simple testcase, this is just the 0ad main menu, with the patch I can see a corrupted menu (a menu texture is grey).
