When I edit text on some web pages in Firefox the some of the characters are slightly moving around their original position.
Each time I type a character or move the cursor or hit delete
or BS
, the spacing of some character in the text is slightly adjusted. As a result, some characters are kind of "shaking" while I type which bugs me.
Chromium behaves perfectly well on the sames pages.
This issue occurs for instance when I am on my NexCloud pages.
I have Kubuntu 20.04 and Firefox 82.0(64bits) but I noticed this for quite some times now with former versions of Firefox and Kubuntu.
I have the same issue on another computer with a relatively fresh install of Kubuntu 20.04.
I thought I would find some posts about it but apparently nobody was bugged enough to post.

After some tests with fontconfig, I found a solution by disabling full hinting on Roboto font.
In
/etc/fonts/conf.avail/56-kubuntu-noto.conf
replace :by :
You must quit your session and reconnect for the change to be effective. I am not a fontconfig expert. Maybe there is something better to be done, but it works for me. Since this file comes from the
kubuntu-settings-desktop
package, I assume this is a Kubuntu only issue.
