MacOS: The Liquid Glass effect does not look native.

[surya-sh]

Issue Description

The current glass effect renders red color too intensely and overall does not look native.

Expected Behavior

The glass effect should look similar to how the right click menus should look

Actual Behavior

The rendering has a red tint like effect. It is not an actual tint but whenever red color is in scope it takes up the whole spectrum.

Reproduction Steps

1. Set background-blur = macos-glass-regular in config
2. Open Ghostty
