Help! Red and green lines streaming from lighthouses in vr

[Tissues]

I must have changed a setting somewhere - tracking works fine and the lines are gone in Home, but when I start a game the view is mostly taken up by the lines streaming from lighthouses in neon red and green.

Not to worry, that's a Steam Workshop add-on you can install via steam. Go back to SteamVR and unsubscribe from the Workshop add-on.

It's this one: http://steamcommunity.com/sharedfiles/filedetails/?id=711411281&searchte
