Hover click target messed up

The only way currently to click the menu items along the bottom of the screen is to move the mouse over the very bottom edge of the border of each item. If you approach from above the button, it isn’t clickable until you hit the bottom edge. Attaching some images to illustrate (my mouse cursor is gold, sorry)

Hmm, I’m not seeing it–which browser is it?

Hmm… very strange. just tested it again today. It’s not doing it… a mystery.
