Summary0009485: Display of midi automation remains after automation points deleted
DescriptionAfter deleting all automation points in a midi region, changing zoom or moving the canvas shows visually the points that were just deleted as if they had not been deleted. The issue seems to be graphical only, as the automation lane's value does not change when playing through the region.

Note that this happens only when deleting all points. Deleting a single point does not have this issue.
Steps To Reproduce1. Create a blank MIDI region in a MIDI track. Something four bars long is sufficient.
2. Add an automation lane to it (such as Pitch Bender or Controller).
3. Add some automation points using the Draw Tool (D)
4. Using the Edit Tool (E), click on the automation lane that contains the newly-created points.
5. Press Ctrl+A to select all automation points in that lane.
6. Press Delete to delete all points.
7. Zoom in or zoom out to see the ghostly remains of the automation points that were just deleted.
Additional InformationThe attached screenshot shows the result of deleting all of the automation points and then zooming out one tick on the mouse scroll wheel. The automation points that existed in the previous zoom level are displayed beyond the boundaries of the region at the current zoom level. (There should not be any points at all, since they were deleted.)

Unsure if this is an issue on my system only. So, here are my system specs just in case the issue is indeed unique to me.
