For driving I recommend Magic Earth, it’s based on OSM data but uses proprietary traffic information as well

No, it’s a standalone application

Oh but this solution defeats the purpose of even using Kodi doesn’t it? This isn’t switching engines, but rather forcing Kodi to open files in an external application

that would be great, but how to do that?

Perhaps something’s wrong with your display

tried this and seems Jellyfin is handling it well
