Created attachment 64875 [details] Pink bullets on blurred areas Version: unspecified (using KDE 4.7.2) OS: Linux When I set Blur strength to maximum, I get pink bullets and painting issues on blurred areas (panel, plasma extenders). Mesa 7.11 on Kubuntu 11.10, Intel i915 driver. When I change blur strength back to another value, the issue vanishes. Reproducible: Always Steps to Reproduce: 1. Have an Intel graphics with i915 driver 2. Set blur strength to maximum Actual Results: Panel, plasma extenders, etc. (blurred areas) get pink bullets drawn over them. Expected Results: Panel is really blurred

could you add an "glxinfo -l" output.

It's most likely an indirection issue and i somehow doubt this: > GL_MAX_PROGRAM_ALU_INSTRUCTIONS_ARB = 16384 > GL_MAX_PROGRAM_TEX_INSTRUCTIONS_ARB = 16384 > GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB = 16384 > GL_MAX_PROGRAM_NATIVE_ALU_INSTRUCTIONS_ARB = 16384 > GL_MAX_PROGRAM_NATIVE_TEX_INSTRUCTIONS_ARB = 16384 > GL_MAX_PROGRAM_NATIVE_TEX_INDIRECTIONS_ARB = 16384 ... a lot ;-) Native one should be more like "4", so there's likely sth. broken in the driver/setup. Is the issue still existent?

At least with these the shader should not hit any limits :-)
In 4.8 the pink bullets only appear when disabling the new "Save intermediate rendering results". When this option is checked, everything works fine, if it is not checked, the bullets appear as stated above.
Seems to work now on OpenGL version string: 2.1 Mesa 8.0.2 :-)
ah an upstream which is upstream. just for the record: could you please attach a glxinfo -l so that we can see whether the values are correct, now?

The values look pretty much the same as before.
couple of ARB limits were indeed raised what might be related - GL_NUM_COMPRESSED_TEXTURE_FORMATS_ARB = 6 + GL_NUM_COMPRESSED_TEXTURE_FORMATS_ARB = 2 - GL_MAX_PROGRAM_PARAMETERS_ARB = 1024 + GL_MAX_PROGRAM_PARAMETERS_ARB = 4096 - GL_MAX_PROGRAM_LOCAL_PARAMETERS_ARB = 1024 + GL_MAX_PROGRAM_LOCAL_PARAMETERS_ARB = 4096 - GL_MAX_PROGRAM_LOCAL_PARAMETERS_ARB = 1024 + GL_MAX_PROGRAM_LOCAL_PARAMETERS_ARB = 4096 - GL_MAX_VERTEX_UNIFORM_COMPONENTS_ARB = 4096 + GL_MAX_VERTEX_UNIFORM_COMPONENTS_ARB = 16384 - GL_MAX_VERTEX_TEXTURE_IMAGE_UNITS_ARB = 0 + GL_MAX_VERTEX_TEXTURE_IMAGE_UNITS_ARB = 16 - GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS_ARB = 16 + GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS_ARB = 32 - GL_MAX_FRAGMENT_UNIFORM_COMPONENTS_ARB = 4096 + GL_MAX_FRAGMENT_UNIFORM_COMPONENTS_ARB = 16384
It seems Blur’s caching capabilities are quite minimizing this issue but I was playing around a bit and the issue is still present. Sorry for the noise.
