I’m on the beta 2, it’s still hard to read. My background has a very light sky with a dark tree. The buttons seem to adjust for the dark tree, meaning when the buttons are over the light sky (which is in the middle of the screen, where the buttons normally are…) it is unreadable! It’s better when the buttons are over the dark tree (still quite hard to read though), but that’s only when I have half swiped up…
