Message : Vulkan: Don't always end the render pass when updating the scissor We don't always need to end the render pass when updating the scissor, since it will be ended later when necessary. This change is in preparation for optimizing resolving multisample images with glBlit, since the render pass needs to be updated before it's ended.
