Description Rubén Fernández 2011-01-04 13:01:55 UTC
The game "Doctor Who: The Adventure games" produces polygon artifacts when
using GLSL; turning off GLSL in wine makes the game render correctly; using
GLSL with software rendering / llvmpipe renders correctly as well.

Some vertices are incorrectly translated

Hi, Can you try with the debugger branch from git://anongit.freedesktop.org/~tstellar/mesa and post the output of RADEON_DEBUG=vp ? This branch will probably mis-render a bunch of stuff, but it produces more helpful output.  Also, If this branch causes a segfault, can you post a stack trace?

I've tried, but it's missing the file "radeon_debugger_result.h"; please add it and I'll test with it as soon as I can.

radeon_debugger_result.h

Sorry, Add this file to src/mesa/drivers/dri/r300/compiler

Done; it doesn't segfault, but aborts due to "cannot allocate memory" before even getting to the point where it renders the characters wrongly; it seems to compile the shaders anyway, so I'll give you the log.

Does running mesa master branch with RADEON_DEBUG=noopt fix the issue?  If so, can you post the output of RADEON_DEBUG=noopt,vp ?

It doesn't - the results are the same. Posting the output anyway, in case it helps.

Since I no longer have access to an r300 card, I can't test for this bug anymore; unless somebody else has such a card, and this same game, I guess it's better to mark it as "solved".
