Bug ID: 164466
Summary: Severe lagging while scrolling and typing on Linux
Product: LibreOffice
Version: 24.8.4.2 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: [email protected]
Reporter: [email protected]
Description:
libreoffice is lagging while i'm scrolling or typing.
the lagging has been occuring at least since my OS (Fedora) is using plasma 6
(but i can’t rule out wether the problem has occured earlier, because i haven’t
been using libreoffice much back then).
i tried measuring the cpu load, but i didn't recognize anything suspicious.
notably it only happens on my laptop but not on my desktop-pc, although the
software-configurations (OS etc.) are identical.
i tried unsuccessfully:
- using the .rpms from the fedora repsoitory (with gtk and kf6 backend)
- using the flatpak version
- using the appimage version
- enabling/disabling the “wayland”-permission of the flatpak version (i.e. the
lagging occurs on wayland native and xwayland as well)
- enabling/disabling the “direct graphic rendering”-permission of the flatpak
version
- enabling/disabling screen zoom at OS level
- enabling/disabling adaptive sync at OS level
- enabling/disabling the “[ ] use hardware acceleration”-checkbox in the libre
office settings (section: libre office → view)
- enabling/disabling the “[ ] use anti-aliasing”-checkbox on the libre office
settings (section: libre office → view)
- enabling/disabling the “[ ] smooth scroll”-checkbox in the libre office
settings (section: writer → view"
- i tried scolling with the mousewheel instead of the laptop’s trackpad
- i tried different icon themes
- trying different (or disabling completely) the power saving modes
- using different files: it occurs even on very "basic" files, like writer
(i.e. .odt) files that only contain text.
- trying a clean user profile

ryzen 2700x (8-core), 32 ddr4-2933, radeon r9 380 4GB
=> i guess the problem is somewhere in the graphics stack, as the GPU is the
only major relevant hardware/sofware difference between my desktop pc and my
laptop.
Steps to Reproduce:
1. open libreoffice (e.g. writer or calc)
2. type and scroll
Actual Results:
severe lagging
Expected Results:
smooth typing/scrolling experience
