Hey, I seem to never learn as I also had issues when updating to catalina, same again for big sur. After updating both my macbook and work mac, both had the exact same issue. (using VW 2019 SP6) when doing anything on screen, eg moving, copying deleting, the screen does not update my actions, until I scroll in/out to zoom, this then updates the actions I have committed. its not as bad as the catalina issues where I had memory leaks and can be worked around, more annoying than anything to have to update the view by scrolling every-time I do anything...
