This is a function of the database that has been addressed in the forthcoming release and you will see addressed in PADS 9.2. There are no workarounds to the issue in the current release.
Thanks for the feedback.
We will check the behavior of the 9.2 beta version soon and will report our findings.
I have checked the Display behavior of the PADS 9.2 beta1 today:
The above described behavior - screen refreshes at almost every action - is gone.
The schematic window now acts as expected (There is only a small
discontinuation sometimes during vertical scrolling - that's ok.).
