Clicking on a different tab or moving the mouse out and back into the area does not remedy it. Reproducible: Sometimes Steps to Reproduce: Could not reproduce. Goes away if the window is closed and reopened or if a Tab is dragged out into its own window. Actual Results: Mouse flickers. Expected Results: Mouse stays at arrow (default) cursor. This is 3.5 beta 4. I apologize if I was supposed to report those somewhere else.
