Description:
So, actually this isn't first I got this bug, except for scrolling bug.

This bug (flickering UI) happen to me in first installation on Linux with Cinnamon desktop environment. I don't know what's the problem, but when i use XFCE or Bspwm it run normally, no bug, no following scroll, no slowdown/lagging. If I use VCL X11, it run normally too.

Maybe that's from Cinnamon or my graphics card issue, but if I report to them, I'll be told to report to libreoffice team later, but if I report here, I'm told to report to Cinnamon team. So yeah i don't know, I'll just report it here.

For attachment of log? I don't know what i will attach because when i run from terminal it's show no error. But you can see on this video,

VCL X11 Generic, https://www.youtube.com/watch?v=3QImhq4_vwg
VCL GTK3, https://www.youtube.com/watch?v=o4vbgVWbono

Steps to Reproduce:
# Flickering Issue
1.Open LibreOffice Writer, Calc or more from LibreOffice suite.
2.Flickering and slow starting

# Scrolling Issue
1. Open program LibreOffice suite.
2. Scroll the style format in right (standard UI) or top (Tabbed).
3. The page following scrolling too.
4. If select some style and scroll, the page will not scrolling anymore.
5. But, if select the page, it will following the style format.

Actual Results:
Lagging, Slowdown, Flickering, Scrolling bug.

Expected Results:
No lagging/slowdown like generic backend (VCL:x11) and no following scroll when style format scrolling.

I am experiencing this same issue, most notably in Impress. I'm running 7.4.2.3 but have seen this consistently in previous versions. Sidebar menus (on the right, Properties, Styles, Gallery etc.) will flicker when I move my mouse cursor on the screen.

Similar issues I've seen elsewhere suggest that this is a GTK-3 problem, and recommend disabling hardware acceleration and disabling background cache options. Neither suggestion led to any improvement.

See bug 144813 comment 8. Do you have GTK_IM_MODULE=xim environment variable set in your .xinputrc file? https://askubuntu.com/questions/1388589/libreoffice-7-2-5-2-ubuntu-20-04-1-lts-flickering-menus-and-right-panel/1434282#1434282
