robegue, I'm not convinced we have an actionable issue here that needs to be addressed via scheduling resource now. This is how to have a few seconds in scrolling the attached picture is expected here.
Also, it matches the speed with which Office does the scrolling. Hence, for now, this is a Won't Fix Wishlist request, focused only on the attached document, pertaining to the underlying algorithms regarding image presentation to be faster, more efficient, etc. which will be addressed over time upstream. If more information is presented that provides a materially new insight, then this is a different matter, and the Status may be reconsidered. Despite this, the discussion may still continue regarding this issue. Thank you for submitting this report, and working together with me on this. ** Package changed: xorg (Ubuntu) => libreoffice (Ubuntu) ** Changed in: libreoffice (Ubuntu) Importance: Low => Wishlist ** Changed in: libreoffice (Ubuntu) Status: Incomplete => Won't Fix -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1405084 Title: Scrolling takes 5 seconds holding down arrow key at 100% zoom Status in libreoffice package in Ubuntu: Won't Fix Bug description: At 100% zoom, I count about 5 seconds to scroll from first to second page by holding the arrow-down key. CPU is not occupied by any other program. At 180% zoom, I count about 18 seconds to scroll from first to second page by holding the arrow-down key. At 180% zoom, a two-pages text-only document takes less than 2 seconds to scroll from first to second page by holding the arrow-down key. It becomes faster (not much) when the same image covers a smaller area. From settings, I've tried to maximize the graphics memory, and to enable/disable hardware acceleration and antialiasing, but it doesn't help. The problem persists in LibreOffice 4.3.5-rc2 from ubuntu PPA.
