Description Gary 2020-12-28 12:03:32 UTC

Description:
Win 10 scrolls fine in Edge, Opera, Wordpad, etc., but LibreOffice is almost impossible to scroll with, about 5x too fast and jerky

Steps to Reproduce:
1. Open an existing multi page RTF document.
2. Try scrolling & notice how it is too fast.

Actual Results:
Too fast and jerky scroll

Expected Results:
Smooth scrolling 


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
-Smooth scrolling. 
-I’m using Lenovo ideaPad Flex 5 14 with Win 10 Home 1909 up to date.
-I upgraded from 7.0.2.2 and the problem remains.
-S/W should just use the default touchpad settings that works fine on other apps.
-OpenGL is enabled.
-This has been an ongoing issue, listed round about as “Is it possible to adjust scrolling speed in all LibreOffice apps?” It was closed on 2020-10-12 by Alex Kemp with an insufficient reason that did not address a fix for people in 2020 still having this issue on newer hardware.

Didn't notice anything obviously wrong in the scrolling area. And the OpenGL part doesn't make much sense.. 7.0 uses Skia Raster/Vulkan (OpenGL is still present in a hidden corner of the code.. but more a temporarily left over for testing purposes.

Please copy the help-about Window. And consider resetting the profile. Help -> Safemode. 

If that's still not helping: Tools -> Options -> view -> Check Force skia sofware and press OK & restart..

What device do you use for scrolling? Mouse wheel? Page down key? Touchpad?

I am not the OP, but a random person who just came here to report the same problem. I am using version 7.0.4.2 on Windows 10. The scrolling speed of mouse wheel is all right, but with the touch pad (Microsoft precision touchpad: https://docs.microsoft.com/en-us/windows-hardware/design/component-guidelines/windows-precision-touchpad-implementation-guide ), the scrolling is too fast, especially when the document is zoomed in (like the "Optimal" zoom factor).

I do not have this kind of problem with modern browsers like FireFox, even if the web page has been zoomed in (pinch-to-zoom on the touchpad). When using 170% zoom in FireFox so that a Wikipedia article fits the width of the screen, swiping up about 1 cm scrolls down the document by about 1 line. Doing the same thing on Writer, with Optimal zoom, 214%, the document is scrolled down by about 14 lines.

Please test scrolling with touchpad of on a laptop with a Microsoft precision touchpad, which is sort of the standard touchpad type for most modern Windows laptops.
