Graphics settings/rendering effects -> Local lights, fog, bloom can't be selected
If graphics is set to custom, and rendering effects to "enabled", the last 3 options can't be clicked.
I'm getting the same problem running PR1200 which was built against master 21 days ago.

I do not believe this is an issue as you are not able to turn that on or off separately. It's either they're all on or they're all off.
Feedback from meeting: while this behavior is correct, it's probably bad UX to show users these buttons if they are unable to check / uncheck them, it might confuse them as to why it's always greyed out. We should instead have "Local Lights, Fog, and Bloom" in parentheses next to the rendering mode switch.
