I run in two column mode, and when using auto complete in the right column any changes to the layout of the auto complete dialog once it's up (more typing to change results/etc) will cause the entire view to shift to the left ~10px and then immediately back to its original location. As a result, the entire view bounces around while typing and makes things unusable. I had to disable auto complete to regain my sanity. The behavior does not reproduce in the left column.
