Jumping viewports


When running scripts I oftentimes get the viewports to jump back to previous views.
As if for the viewports display an outdated cached version of themselves.
It feels like a bug or at least an oversight. It’s confusing at times to all of a sudden se a previous state of the file.


This has existed since V4… You’d have to search the original newsgroup archives to find initial complaints/discussions about it. It used to be much worse, for example running some heavy normal Rhino command would revert the viewport back to a previous buffered version for many seconds until the command completed, which was very disconcerting. It was partially fixed in V5, but you still see the reversion from time to time for an instant, V6 as well.
