            Bug ID: 157494
           Summary: Track-pad scrolling in Flatpak Writer is slow and
                    laggy.
           Product: LibreOffice
           Version: 7.6.2.1 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: [email protected]
          Reporter: [email protected]

Description:
Scrolling using track-pad on writer is not fluid and feels laggy. Comparing
with scrolling on Firefox and only-office where scrolling is smooth.

Troubleshooting tried:
1. Scrolling performance on Native distro version is same as flatpak version.
2. Turned on smooth scrolling option without any effect.

Is there any other information which I can share which will be helpful?

System Information:
DE: KDE Plasma 5.27.8 [Wayland]
Distro: openSUSE Tumbleweed
Display:2560x1440 [150% scale]
Refresh rate: 165 hz

CPU threads: 16; OS: Linux 6.5; UI render: default; VCL: gtk3
Locale: en-IN (en_DK.UTF-8); UI: en-US

Steps to Reproduce:
1. Open .docx word file.
2. Scroll using two fingers(fast or slow) on touch-pad [Native-scrolling turned
on].
3. Document scrolling feels laggy.

Actual Results:
Scrolling is not smooth on 165 Hz display on 150 % fractional scaling.

Expected Results:
