Add a CommentI have exactly the same issue on macOS. Mine blows up on the PDFView drawPage:toContext. Happens when doing a stress test alternately opening and closing two PDF files. Some crashes on the first close, some on a later close.Suspect "stale" window update events that trigger PDF page redraws after the user has clicked on the window close button. What am I missing?
