It seems that Dynamic Surroundings' Light Level viewer fails to render if 'AoV-1.12-0.9.2' is installed. It's not only just Dynamic Surroundings but it seems to also affect More Overlays, Not Enough Item's Mob Spawn Rendering & Light Level Overlay Reloaded.
Here's an image of the bug using 'Dynamic Surroundings'.
Left is with AoV installed, right is without AoV installed. An older version before the current one didn't have this issue if I recall.
EDIT
The version I was using before the update was 'AoV-1.12-0.8.14' and the issue doesn't occur. Versions above that and the issue occurs.
