Issue description

Tweaking rendering/reflections/reflection_atlas/reflection_size has no effect until reloading the project, but I was not prompted with reloading it like it is the case with some other settings.

This is the message that I expected to show:

Steps to reproduce

• Open a project
• Modify rendering/reflections/reflection_atlas/reflection_size (found under Rendering -> Reflections -> Reflection Atlas -> Reflection Size)
