Description lordmethenor 2025-09-07 16:35:02 UTC
Description:
Scrolling with the touchpad is now very jerky/laggy/unresponsive/uneven, especially when moving quickly. Downgrading my flathub installation from 25.8.1.1 to the last 25.2 release available (commit 59d9271877f281464e88f9df883c92df19e8bdef65fe43aea9169b799d8d64fd) restored predictable scrolling.
It does seem like low-velocity scrolling may be improved from 25.2, but big jumps work less well.
This does not affect arrow key or scrollbar scrolling.

Steps to Reproduce:
1. Open new document
2. Use two fingers to scroll on touchpad

Actual Results:
Scrolling is broken

Expected Results:
Scrolling is (relatively smooth) or at least predictable


Reproducible: Always


User Profile Reset: No

I updated to the latest flatpak, which still reads 25.8.1.1?

Version: 25.8.1.1 (X86_64) / LibreOffice Community
Build ID: 54047653041915e595ad4e45cccea684809c77b5
CPU threads: 16; OS: Linux 6.16; UI render: default; VCL: gtk3
Locale: en-US (en_US.UTF-8); UI: en-US
Flatpak
Calc: threaded

and it is working well again. I don't know if I can replicate this again.

And...it's happening again. I don't know what "fixed" it. Maybe because I was testing with a blank document?

I have a similar issue. Using LO 25.8.1.1 results in VERY choppy scrolling when using either the touchpad or the scroll wheel on a mouse. Dragging the scroll bar results in smooth and responsive scrolling.

I am also using the flatpak version and I can confirm that downgrading to 25.8.0 or 25.2 resolves the issue.

Additionally, it seems like the problem might be linked to using scaling factors above 100%. I use my computer with a 125% scaling, but testing a few documents with a 100% scale resulted in smooth scrolling. I also tried 200% scaling and scrolling was still choppy, so it seems to only work fine at 100%?
