This only happen when i’m piloting a spotlight. I’m also pretty sure that the arrow that identifies the direction the light is moving in is the cause. Does anyone know how to fix it?
Yes, it is because of the arrow, The only way is to close the eye in the world outliner.(which then also means the only way to select it is via the world outliner)
Not sure why this would come up often enough to be a problem though, first time i’d ever seen this function used 
Hello -
While in Pilot Mode you should be able to hit “G” to go into Game View Mode and all widget related iconography will disappear from the camera’s view including the red arrow. You will need to Hit “G” again to have them return once finished.
Thank You
