Libreoffice Calc two fingers scrolling slows in Window Manager

Hi everyone, I am new here.
I’m not sure it is real problem for others but I noticed this is something.
The Distro is ArchLinux.
I have a Libreoffice Calc spreadsheet with over 3000 rows and 30 columns.
If I open it in KDE Plasma 5, two fingers scrolling on touchpad of my laptop is very good and everything is normal.
But if I open it in DWM window manager, the two fingers scrolling on touchpad of my laptop is very slow while draging scrolbar is normal. I increased the number of memory cache in Tools>Options>LibreOffice>Memory. But not really improvement of two fingers scrolling. I also change some synaptic settings, but no luck.
Please comment if anyone also has an issue like and if there is any solution.
