I have just released update for Mapbox GL QML plugin which should fix the issues exposed by Laufhelden.

Now, when pushing updates of the sources, the sources stack is checked whether any update is pending and, if it is, its dropped in favor of the new one. Has been tested against adding, updating and removing sources.

@jdrescher, would you mind to test whether it fixed also the issues woth longer workouts?

Update is available at OBS and OpenRepos.
