Depth fade flickering on es2

It happens in some devices and randomly. We use it on water foam effect and start to notuce artifacts.
we have water plane scaled to 1 1 1
incresed bounds 10

Nothing helps

We have a beta…d.KittyCatLand

The island at the begining has the flickering

I think this relates to devices drivers. Only way to fix this - disable depth fade by some quality switcher or so on specific devices.

materials can switch for quality, but how can for devices?
