Yes, I’m having the same issue with my XR as well...constant flashing/ refreshing, and has been getting worse...but ‘only’ when I’m navigating with the compass function. If I just have the map up, it works fine; once I toggle the compass icon at the top away it goes! (Photo)
So for me it is a conflict between the map and compass; may be something the devs could look at to see what is happening there...
