Since the first public release of Windows 11, I have noticed that the shades of the windows have become more prominent. Of course this is only the case of the apps that adopts the OS' native window framework and DWM, which I suppose include Firefox.
However, Firefox has something unique when it comes to window's shades. As shown below, the shade of a Firefox window is clearly darker than that of Edge's. It looks almost 2.5 times as thick as the latter. Whilst all the other apps are having normal shades of their windows.
（Same system settings, window position(snapped to top-left) and content within each window on purpose of variation control. ）
When working with a non-full screen Firefox window under light theme, the shade is so noticeable that it distracts me sometimes. Despite visual disturbance, such a dark boarder around window also leads to eyestrain.
Even Windows system doesn't know how to handle this shade, below is the Task-View button float preview of a desktop with a Firefox window on it.
Am I the only one who is experiencing this? Is this a design on purpose or a random glitch? I wish to have my Firefox window's shade behave like all the other native Windows 11 windows'.
Best Regards!
