Some new/additional information.
While I understood originally that the problem occurred immediately upon loading a page, that was incorrect. The problem occurs when pressing PageUp or PageDown, which on a Dell XPS 13 is a combination of the Function key and up arrow (or down arrow). When the problem occurs, as soon as the keys are released, the page immediately continues scrolling in the same direction; i.e., if PgDn, it scrolls to the bottom, if PgUp, it scrolls to the top.-- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
