The artifact disappears if I scroll page down until the line hides below the bottom of the window, but it reappears in the same spot if I scroll up until the offending spot hides above the top of the window. The problem is intermittent but frequent. I cannot cause it to appear reproducibly, but after enough typesetting it is certain to reappear. It is a very minor inconvenience but I am wondering of others see this. I’m on TS 3.36.1. </div><div><br></div><div>Themis</div><div><br></div><img apple-inline="yes" id="5DAB9549-6310-451A-AEE3-025449189F89" height="806" width="755" apple-width="yes" apple-height="yes" src="cid:BFA76910-D6C6-4010-BFDA-EDEB691A5BA0"></body></html>
