Windowing options ( Under the green traffic light in the window chrome ) have no visible icon

Apple M2 Pro, 16GB memory, Sequoia 15.7.4.

When I right click on the windowing options the icons are not visible.

When I mouse-over the position of the icon a checkmark is displayed.

The behaviour works, so I can select an option, even though the icons are not displayed.

Thanks for reporting. Let me look into this. I suspect it has something to do with the code that gets rid of all the annoying menu item icons.
