After an update of a Garmin GPSmap64s via Garminexpress the daily gpx tracks (e.b. 2021-11-08) are not displayed in Qgis 3.20, but only when I zoom in (between 1:10000 and 1:25000, >1:25000 works fine, scale dependent visibility not active). The identify tool responds with 'No features at this position'(zoom to layer works fine).
When I load the 'Current' track (kind of working track for the day) it works fine, visibility & identify. Even after saving the gpx to a shape or geopackage the problem is the same. Same problems with Qgis 3.8
Does anybody know the reason and a solution?
Edit: Problem persists even in print composer: when zoom in, in the print composer the track disappears.
In Garmin Basecamp gpx: no problem
In Google Earth kml: no problem
In Qgis kml: same problem
I tried several ways of 'save as' to different formats, in Qgis the layer always disappears and identify tool does not found a feature, in other apps in works fine. Only with track files recorded after update.
File structure in Notepad++ seems ok. I am really lost at this point...
11-06 should work fine
11-09 shows the problems
