Recently I noticed an issue of the Minimap display, with Google Maps as maps provider:
When driving, the display very often isn't fully updated, i.e. only the layer with the colour areas of the streets, fields, woods etc. gets updated, but the contour lines of the streets etc., as well as the street names and other texts and also the 3d buildings and traffic informations (colour tint of the streets) are missing in the display.
Since often I see one Google Map tile (the one I'm currently driving in) with correct display and another (the next one in the direction that I'm driving to) with the missing contour lines etc. as described, I first thought that mobile data access is missing, so FCC cannot load the new tiles it needs.
But as I tested yesterday and today, this is not the case, because I checked if mobile data access was available, which was the case.
Most interestingly, the missing map elements are instantly displayed when I swipe the map with the finger, without missing map data being loaded (which would take some seconds, as I know from regular MiniMap usage). So the map data (map tiles) are already cached in memory, but only displayed when manually swiping the map, but not displayed when the MiniMap just does it's auto-update based on GPS position.
Unfortunately I cannot provide you a video, because I cannot and will not take a video when driving. But I hope that the descriptions that I gave are detailled enough. If you need more infos, please ask.
I don't know exactly when this issue started to happen, e.g. if it started with one of the latest beta versions.
Did you change anything MiniMap or Google Maps API related? Also, could this bug have been introduced by Google, so you have to update some code related to the Google Maps API?
since long time I use the app Mock Location Path to test navigation software in a nearly life scenario.
Mock location path sends fake GPS routes instead of getting real GPS in the lab.
Nice thingy to check if the navigation does the turns, notification... you name it.
May be this is something you can use for a video instead.
