That is a sledgehammer approach to fixing a visual glitch that was introduced in one of the last couple updates. This really needs to be fixed in your program and have an update released.
We are experiencing this on several computers. Switching to top bar, and then back to side bar, temporarily fixes the glitch. As soon as QuickBooks is closed and reloaded it comes back. Asking us to backup and reinstall is an unacceptable solution. This isn't a corrupted file issue, it's a programming error on Intuit's part.
