When scenes only have a world probe the world probe had several artifacts. - The first sample didn't update the world. - When switching between viewports the world didn't get updates - When rendering it ignored the resolution that was set by the user The reason was that the ubo was only updated when the probes where synced. This PR adds an exception to also update when there is only the world probe. Pull Request: https://projects.blender.org/blender/blender/pulls/110238
