Description

If you open a view when you have a few graphs opened (ie. 8 graphs) it will display an odd visual bug as well as a slight amount of lag. The more graphs opened, the worse the problem is.

Steps to Reproduce

@aldebaran30701 and I were discussing this and we believe that what's happening is each individual graph is being resized when a view is open, which would be why it lags more depending on how many graphs you have open. A potential solution could be to only resize the active graph and then resize the other graphs individually later on as necessary.

The flicker with a single graph is also noticeable and good if we can fix. (Slow motion:) slowed-flicker
