The assertion is triggered because i915-class hardware cannot render to A8 surfaces. The part that's odd is that the same error is not triggered for the other alpha formats. Looking in intel_tex_format.c, MESA_FORMAT_A8 is used for all of the alpha-only texture formats. I'll poke at this a bit. This should be fixed by: commit 78a340fd487c56468ace7347a53f95a0c751c419 Author: Ian Romanick <ian.d.romanick@intel.com> Date: Tue Nov 23 16:17:21 2010 -0800 i915: Disallow alpha, red, RG, and sRGB as render targets Fixes bugzilla #31832 NOTE: This is a candidate for the 7.9 branch. mesa: 78a340fd487c56468ace7347a53f95a0c751c419 (master) Verified fixed. |
