Description
It's enough to launch Examples/Qt-5.15.10/location/mapviewer/ example on Linux Desktop or Android, and application completely freezes, though it manages to draw interface (at least?) once.
This does not reproduce with 5.15.9.

Originally I've discovered it with here plugin, but it's the same with osm plugin as in mapviewer example.
