bug#45640: 28.0.50; Fringe icons show fixed white background on secondary display (macos)

[Li Feng]

1. Use a dark theme (so that it's easier to see the incorrect background
color)

2. Start Emacs on internal laptop display, and observe fringe icons
(eg. new line indicators) are displayed correctly.

3. Drag the Emacs window to the external monitor, and observe the fringe
icons are all displayed on white background instead of theme color.
