I had a bug that was even worse, and I never found a workaround for IE11. In this case I had some kind of progress bar that was updated while a report is being generated. When the report is completely generated, the progress bar is replaced by a button. Except in IE11. At some point the progress bar stopped updating and it never turned into a button. Until you opened the developer tools and IE11 "flushes" the DOM and paints the new situation. So, never having found the cause, we recommended that (internal) customer to use F12 regularly on that page.
