When combined with window_background_opacity, configures the blur radius amount used by macOS when compositing the window on the screen.

This can be used to produce a translucent window effect rather than a crystal clear transparent window effect.

The screenshot below was achieved using this configuration:

lua
config.window_background_opacity = 0.3
config.macos_window_background_blur = 20

The default value for macos_window_background_blur is 0.

See also win32_system_backdrop for a similar effect on Windows.

See also kde_window_background_blur for a similar effect on KDE Wayland.
