With depth bias enabled, RADV sets POLY_OFFSET_PARA_ENABLE in PA_SU_SC_MODE_CNTL next to the front and back enables, whatever the topology; vkQuake's draws carry 0x3a46. The bit applies the offset to points and lines, so it changes nothing for triangles, and Vulkan applies depth bias only to polygons. It is now accepted with depth bias on triangle topologies; point and line draws with it are still rejected. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |
