Alpha-Clamp effect renders differently on WebGL? (AppleGPU)

Hello,

I was following this water physics tutorial. Which uses Alpha-Clamp Effect on an entire water layer.

construct.net/en/tutorials/create-water-games-2172

The tutorial is 4 years old. Maybe WebGL changed its rendering since then. But I get a different result from what I see on his screen.

(I also get a different visual result on preview (WegbGL2) compared to what I see on my own Construct Editor. )

Could anyone clarify for me why rendering of my water-drops change when i hit preview. Compared to what he sees when he hits preview?

I will be providing visuals now. Screenshots from my machine.

Further information:

I can only get rid of this weird glowing effect (which I don't see on the tutorial) on WebGL preview by;

changing the RGB Color value of sprite to white and then changing all sprite instances color value to desired blue color. only then I can get a flat color. without glowing whites around it.

There were some changes to alpha clamp in r365, you can read about it here: https://www.construct.net/en/make-games/releases/beta/r365
