sample KML track

SUMMARY


STEPS TO REPRODUCE
0. vist ridewithgps, search near Waynesboro, VA keywords FFBF 2019 Sun
1. https://ridewithgps.com/routes/28902859
2. Export GPX -> other formats
3. download KML and XML or use attached file
4. Launch marble with one or more KML or GPX files listed on command line


OBSERVED RESULT
Tracks are only visible when panning/zooming with mouse.  As soon as you stop, map appears to be redrawn without tracks.   APRS (if enabled), placemarks, and navigation route (if any) are still visible.   Persists with various basemaps such as openstreetmap, vectorosm, atlas, satellite.  If you pan and let coast, track is visible until map comes to rest.  Problem persists whether hillshading is on or off.  Same for coordinate grid.

EXPECTED RESULT
tracks always visible except when hidden from file panel.
