no smooth scrolling with xfwm, kde and gnome - why?

#1 Post by betazoid »

hi,
I have tested several distros and desktop environments - result: scrolling is not 100% smooth in Gnome, KDE and Xfce, especially in Firefox and Chrome. There is a very slight jerkyness. What is the reason for this and is it possible to tweak something here? Does it only occur with my hardware (Intel HD graphics 520 or something like that)?
However, I made the experience that scrolling is 100% smooth with the following window managers: Marco (Mate), Compiz and Openbox (and Windows 10).
Thanks in advance for the answers
Anna

If you think it is the modestteing driver - I think it is not because I have also tried the Intel driver and the result is the same, or at least more or less the same - with the modesetting driver there is quite heavy screen tearing, with the Intel driver, there is more jerky scrolling.

Another output, with Intel graphics driver where the scrolling is less smooth

I use Chromium Wheel Smoother extension on Google Chrome. It has many option settings and greatly improves scroll smoothness. No doubt there are similar extensions for Firefox.

Nobody has the same problem? can somebody at least reproduce this?
Btw, thanks for the answers - I tried all those smooth scroll plugins/extensions - they do not appear to do much, there are also the smooth scroll flags in Chrome

Interesting. The Chromium Wheel Smoother extension is extremely effective on my system.

I found a couple of years back with Firefox and with Waterfox that I'm currently using, that I got better results by going to preferences>advanced>general and unticking "use smooth scrolling", and ticking "use autoscrolling"....Never did investigate as to why that might be. It just gives better smooth scrolling with the mouse in my case..

Well, I tried the smooth scroll plugin/extension again and the result was that it made the jerkyness much worse, but definitely not better

Are you using the XFCE or Compton compositors? You also said that compiz made it smooth, so you could run that in MX.
