Camera screen seems to have shrunk

[red2017s]

Thought I was going crazy, but then my grandchildren noticed it as well. To all of us, it appears that the size of the camera view on the main screen has shrunk by a good inch. Left to right is about 8 1/2" wide as always, but now the up and down is around 5 1/2"------we think it was a good inch wider last week. We have a 2017 90S. Just curious if anyone else noticed this, or whether someone knows of an update that may have done this---or are we losing it? Tried re-booting and nothing changed. Greatly appreciate it if someone could provide the horizontal measurement from their screen for comparison. Thank you in advance
