Resolution Note (2022.2.X):
ToonWater.shader isn't dealing with platform differences correctly. https://docs.unity3d.com/Manual/SL-PlatformDifferences.html
OpenGL clip space on each axis is [-1;1] while other graphics apis have [0; 1] on the z axis, this causes the issue with depth calculations in this shader
