Works fine for me on macOS with

kitty --config=NONE -o shell=fish -o background_opacity=0.5

From your screenshot I would guess its because fish is drawing a non-default color as the background on your system. Only the default background color is made transparent. Run kitty as

kitty cat

and see if it works.

a bit late to the party, but I've been having the exact same issue with my installation. kitty cat renders transparency as expected. However, it's not working when I load kitty normally, and I can see that it's trying to apply transparency as I can see the transparent gaps (padding) around the terminal window. But the main area is completely opaque.

I'm on MacOS Sonoma, kitty v0.30.1, using the nord theme.

Hi, it might not relates to the question, but i wanna ask what's your terminal theme? It looks great.
