Broken interface after update to 26.18

Garmin, what have you done again? I had been avoiding updates for almost a year because your new updates always suck.

I thought that 26.18 was okay—nobody had been complaining—so I updated...
Now, when navigation notifies me of a turn, 1/3 to 1/2 of the screen is blank.

Also, ClimbPro doesn't show the hill.
