Right, we found the root cause for my issue, so we can actually load the correct state here (i.e. create a NUL block and point both depth-stencil and color-calc to it). We could use that same block for the blend state as well, etc. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
