Weird visual thing

[Pacific_Jim]

Apologies if this is a dumb question, but I've had a weird visual bug (or maybe effect?) and I can't for the life of me figure out how to get rid of it. I tried making a new universe, and if it's a setting I can't figure out what I changed. Any help would be appreciated.

That is debug mode. You can toggle it on and off by pressing F1+F10
It is also found in the settings.cfg: P_PHYSICS_DEBUG_ACTIVE

Thanks. I knew I'd have accidentally knocked something dumb.
