Short description of error
The new Cryptomatte node outputs a white RGB value of 2,2,2 instead of 1,1,1 when Multi-View is active and 2 cameras are enabled. If you have 3 cameras enabled, the RGB value for white becomes 3,3,3. If you plug the resulting b/w mask as a factor in a Mix node it causes errors in the RGB values of the composited image. With the Cryptomatte (Legacy) node everything works fine.

Exact steps for others to reproduce the error
Open the file provided and hit render. In the compositor inspect the white area of the matte output with right-click (eye dropper).
