Calling "builder build" (in your refresh method) will reset all "path" objects, so it may happen that you reset the path objects while in the ui thread, they are used to draw the
shapes.

Hi Nicolas,

thanks for the information! I don’t know anything about path objects, so I won’t have a quick fix, but now I know better where to look, hopefully I can find some time, because I still think this way of doing things is interesting.
