Pay attention when there's an object moving in front of a solid color
background. I use the terms object and background very loosely here.
What you should see if your denoise strengths are too high (and maybe
also when using the low-precision denoise3d) is a sort of muddiness in
the solid background where the object has passed over it.

If anyone's interested I could post a short clip from the opening of
SE:Lain where you can see the problem very clearly.
