There are various issues with the lay-out of the model and the way it responds to movement.

Minor issues that have a quick fix:
1) Upon starting, there are artifacts all over the page, but zooming out once removes them.
2) The style (modern) is not applied until you select it again.

Annoying issues that have a quick fix:
3) When saving, the viewport resets to fully zoomed in (original setting). However, it seems the zoom function doesn't understand that it has been reset, so it thinks it is still zoomed out. This puts a fairly large part of the model out of view, with no ability to get it back (except by judicious use of zooming in and out in the right spots). Since I'm on autosave that is very annoying.

Very annoying issue with no fix:
4) When zooming in and out the entire layout shifts. This means all vertical and horizontal lines are now angled. Objects are no longer aligned. Aaahhh!!!
5) If you zoom in and out enough, the whole layout goes to shit, you need to close the file without saving and hope the autosave doesn't kick in because that means a restore from version control.
