When pushing a non-fullscreen gui page above another we can get overlaying Overlay Counters.
Mostly this only results in a darker background of the overlay.
But ingame or when opening Options and changing the displayed Overlay Counters one can clearly see the overlaying Overlay Counters:
This patch fixes that by hiding the Overlay Counters before a new page with overlay is pushed and unhiding the Overlay Counters when the pushed page is closed again.
