Jerky scrolling in Chrome, FF, Brave, VimB

Thursday, 28 October 2021

People,

I have had a reasonably powerful PC for the last few Fedora versions:

   i7-7700K CPU @ 4.20GHz 8 core
   32GB RAM
   40GB Swap
   50% free on 4TB Seagate drive

and even though the PC seems unloaded according to Glances eg:

   < 40% CPU loading
   < 80 RAM used
   ~ 1% Swap used
   - Disk IO minimal

I still have problems using the up / down cursor keys, PgUp / PgDn keys, 
mouse wheel for moving around on web pages - there is usually a second 
or more delay and then a jump . .

Admittedly I do tend to load up the browsers with multiple windows and 
tabs but if the system still seems unloaded, why is there the jerkiness?

Prior versions of Fedora were XFCE4, current F34 is Wayland and Sway but 
the problem has been there over multiple versions . .

Thanks,

Phil.
