First of all, thanks for replying.
Ok I added a millisecond counter. When normally running the program it says it takes about 60-100 ms for one loop. When pressing the right mouse button on the graph or a control the counter goes down to 2-5 ms for one loop. So something happens for sure

Without any actual knowledge of your code, it sounds as if you are sampling in the same VI that graphs the data? If this is the case, it means that your data acquisition is taking place in the same thread as the UI, and is therefore affected by events like the Mouse clicks/window dragging etc.
Youre right. I will have a look into the producer/consumer for displaying the data. But the same thing happens even when the graphs are removed from the VI
EDIT:
After restarting Labview the problem is gone for some time. So maybe it occurs only during development.
