Automatically disabling background opacity with Mac fullscreen doesn't seem to work

[maciejzj]

Hi, I may be missing something but from what I understand from this discussion: #2840, as well as from this fragment of documentation: https://ghostty.org/docs/config/reference#background-opacity, particularly this paragraph:

On macOS, background opacity is disabled when the terminal enters native fullscreen. This is because the background becomes gray and it can cause widgets to show through which isn't generally desirable.

when I enter Mac fullscreen the background opacity should turn off. However, on my system it seems to still be on which causes the undesired effect of widgets showing through.

Here is how it looks like:

compressed_ghostty.mov

Doesn't the actual behaviour go against the documentation? Am I missing something? Is this a bug?

Here's my config:

# Text settings
font-family = Liga SFMono Nerd Font
font-feature = -calt
adjust-cell-width = -5%

# Makes ghostty to fallback to the default block cursor
shell-integration-features = no-cursor

# UI settings
window-padding-x = 5
window-padding-y = 3
window-width = 86
window-height = 26

theme = catppuccin-mocha
background-opacity = 0.8
# background-opacity = 0.96
background-blur-radius = 50

# System behaviour
window-inherit-working-directory = false

# Keyboard settings
macos-option-as-alt = left
macos-non-native-fullscreen = false

(the problem also persists with the stable release from the website/brew as well)
