Separate dirty bit for attrib's binding VBO change Make a separate dirty bit DIRTY_ATTRIB_POINTER_BUFFER for vertex attrib's binding buffer change. So in handling glVertexAttribPointer, ANGLE will only modify a vulkan graphics pipeline when attrib.format, attrib.stride or attrib.divisor change. If only the VBO pointer changes, then Vulkan can update the state via "vkCmdBindVertexBuffers()" without triggering a pipeline update.
