What happened?

When a time is changed in the trainrun dialog window, the data update in the network graphic editor (Editor) is executed quickly. However, if the same action is performed in the graphic timetable (Streckengrafik), it takes an eternity (very long). When a time is changed in the pearls view (Perlenkette) and the graphic timetable (Streckengrafik) is active, the update is much faster, even with relatively large network graphics. This suggests that there is some interaction between the trainrun dialog and the graphic timetable component that is causing performance issues.

Steps to reproduce the issue

1. Open a quite big Netzgrafik
2. Select a trainrun
3. Open the graphic timetable (Streckengrafik)
4. Click on time (number) -> trainrun dialog window opens
5. Change the travel time (for example)
6. wait -> this is quite bad (issue)
