There are at least two screens where this happens.

1) On an RTC target, choose a font large enough so that the item "Set Time/Date" in "General Settings->System->Time & Date" needs to scroll. Then go there, and enter the "Set Time/Date" screen. The string "Set Time/Date" will scroll over the screen. Choosing another language than English might show this problemm earlier, because the translated string for "Set Time/date" might be longer.

2) On an FM radio target, choose a large enough font so that at least one item of the radio context menu needs to scroll. Then enter the radio screen, open the context menu, place the cursor on a line that needs to scroll, and leave the context menu with 'left'. The menu item will now scroll over the radio screen.
