[Ques]: unfocused window is opaque?

[semi710]

can this be controlled via extension? or it is related to OS window compositor?

This is down to the OS unfortunately not even the browser itself. I assume you on Windows or some Linux? On Windows you can use 3rd party tools to fix this and on some Linux DEs I think you can fix in zen about:config , look for "gray" there and I think there was a toggle named gray out inactive windows (I might have added this to the mod but not sure). Try toggling this first and fi not, you will need ot look into the OS.

I use linux as my primary device, but for official work sadly on macos/darwin, Thanks for the suggestion will try that.
