I cannot see native scrollbars in Falkon when using the built-in PDF viewer. Although is not visible, I can scroll if I drag my mouse where the scrollbar should have been. When the option is unchecked, I can see the non-native scrollbar though. STEPS TO REPRODUCE: 1. Enable native scrollbars from Preferences. 2. Open any multipage pdf in Falkon, or zoom in enough on a single page so that only a fraction of the page is visible on the screen. OBSERVED RESULT: No scroll bar on the right side. EXPECTED RESULT: A visible scroll bar on the right side.
