I received my 935 the day before yesterday. After the upgrade to 8.0 (i guess) this phenomenon appeared.
Menu's are almost non readable. I found out that it is worst with a white background. (see the attached video).
With Garmin Support on the phone I did a full reset back to factory settings, but the issue returned immediately at setup already.
So my supplier will deliver a new one, so I can sent back the broken one.
Has somebody of you ever see this behavior before? https://youtu.be/-twm832uCZ0
