Planetarium Display

I have been exploring the settings in Prism and must have changed something I shouldn’t have. Now when I move anywhere on the planetarium display the display updates/refreshes about 4 or 5 times before settling. Any ideas ?

You set the refresh in the skymap config tab as per blelow… in the bottom part

Have you included more catalogues in the display?
I think it refreshes sequentially to update the objects for every selected catalogue
The slowest to update I have found is the Tycho star cat.
