Description Stefano Teso 2011-09-26 07:10:24 UTC 
Hi,

using git 455a19b1b3d7ca0a40c65d89e45209dbd8ac7b35, and running:

$ glxinfo -l > /dev/null

makes mesa sad:

Mesa: User error: GL_INVALID_ENUM in glGetIntegerv(pname=GL_MAX_COLOR_MATRIX_STACK_DEPTH)
Mesa: User error: GL_INVALID_ENUM in glGetConvolutionParameteriv

This doesn't happen with stock mesa 7.11, nor when using LIBGL_ALWAYS_SOFTWARE=1. The driver is r600g, the device is:

01:00.0 VGA compatible controller: ATI Technologies Inc Robson CE [AMD Radeon HD 6300 Series]

I'm using debian unstable FWIW.

Actually, I can reproduce this with a checkout of the mesa-7.11 Git tag as well. Presumably the 'stock' 7.11 you're referring to just doesn't have this error reporting (which BTW usually indicates an application bug) enabled.

I can confirm your findings, git mesa and mesa 7.11 do exhibit the warning, while the debian package does not. There's no difference when using llvmpipe, although I was sure of the exact opposite yesterday. You can close this bug, sorry for the spam.

As mentioned above, I'm closing this bug.
