Classic: glitch in the calendar drop-down
After setting a low resolution (e.g. 800×600) so that the calendar drop-down’s content doesn’t fit and world clocks/weather get a scrollbar, a header’s background seems to cover what’s below it:
Regular GNOME looks correct in these circumstances (although it might be that the lack of the bottom bar gives the clocks section slightly more space, so the bug is not triggered):
