This issue affects me on Ubuntu Bionic 18.04 if I have a Firefox window open with a frequently changing title bar. It seems that plasmashell cannot keep up with re-rendering the label on the task bar buttons. The specific Firefox operation that triggers it for me is using the HTML5 iKVM on a Supermicro server where the title is constantly updating with the FPS of the video connection.
