This Error appears when in the scene view my clipping planes are on near 1e-05. To solve it I had to increase it.
Scene tab → camera icon → Clipping planes → Near → Change value to be greater than 1e-05
This will solve this error and also some lightning glitches
I just fixed the same issue, one of my game Camera had too much difference between min and max (like min 0.03 and max was super high, after removing one power of ten for the max, it stopped this), note that this message was expanding in Edit Mode so even if the game wasn’t running. Fixed.
