I add the grabpass in water shader, it works fine in editor. But in iOS, the z-test is wrong for any pass behind the grabpass, the result looks like water behind mountain become front. When I disabled the MSAA, it works fine again.

env:
unity 2017.3.1p4
iphone se, ios 11.2.5, metal

Last year in my project,I found grabpass+iOS+MSAA = rendering errors.I had to remove grabpass cuz MSAA seems more important then.

After one year,I would like to know is it solved on build 2017.4.26 and later version?

Anyone still following this issue?
