--- Comment #3 from Ilia Mirkin imirkin@alum.mit.edu --- You might try running with ST_DEBUG=tgsi -- should show the failing shaders. Make sure you're on a debug build. MESA_GLSL=dump should be interesting too. [Sadly there's a 4k limit on the dumped shader code size which is likely too short for a lot of shaders...]
