I recently purchased a high-end PC with the highest performance configuration available. In Illustrator CC, when I open a new window for the same file (to view on another monitor), I'm seeing some drop in performance. Specifically, when editing paths in only one window it's fine. The performance is fluid and fast. When I open another window (Window > New Window), there is a noticable difference when editing paths. The handles are jerky and slow when manipulating them. Has anyone experienced this and/or know of a solution? Thank you!
