Perhaps the problem has already been described in #2153
I made a basic example with vector tiles.
It does not work very stably, but it shows that for the "first" view iTowns requests more vector tiles than raster tiles (OSM).
Raster tiles are only requested for zoom level 11, vector tiles for 11 and 10 zoom level. This creates an additional load on backend services.
If the problem is known and duplicates the anything issue, please close.
