Updating a shape takes forever

Fredda

I have a GND shape, covering the entire top plane, which is giving me a headache. Manually updating the shape or any other edit that indirectly updates the shape takes forever. Well, it takes at least between 30 and 60 seconds and Allegro becomes unresponsive during that time. Allegro even shows as Not Responding in Windows Task Manager.

What can cause this behavior? I suspect that there's some setting in Allegro somewhere that should be changed.

I'm using Allegro 17.2 and Windows 10. Computer has an Intel Xeon E3-1505M v6 @ 3.00GHz CPU and  has 32 GB RAM so it should be fast enough.

It's a medium sized board as shown below.

    it talks about allegro package designer but it uses the same pcb editor.

    in addition, i usually set the dynamic fill not as "smooth" but as "fast" to save my time.
