### Bug Summary When scrolling using two finger swipe on a touchpad, the editor scrolls very fast (100s of lines) which makes it unusable
### Details Following steps don't require a strict order 1. Open any (long) file in geany 2. Try to scroll in it (the editor/workspace) using touchpad - it scrolls excessively (unexpected) 3. Try to scroll in the sidebar or message window using touchpad - it scrolls precisely and controllably - as expected 4. Try to scroll at any of these place using mouse - it scrolls same as step number 3 above - precisely, controllable, expectedly
