the slowdown only affects the opening of new WebKit instances, e.g.,
when I launch Evolution, or when I click "Reply to List". To answer your
message, 26 seconds passed between clicking "Reply to List" and the
window opening, something that certainly took less than 1 second just a
few days ago. When I open Evolution, after a short while I can select an
email folder without the email preview already displaying content, IOW
mouse movement and other functions are not affected by this.
As soon as the preview in Evolution displays the contents of a message,
I can select different messages without any delay. However, when I
double-click to open a message window, it takes a few seconds.
Milan, the developer of Evolution, noticed the following in my strace
outputs:
"the above looks like something from a 3rd party web plugin
(AdContentBlocker). It's weird to see any such thing being loaded also
in the Evolution. You might have it installed in some common place all
the web engines looks at."

I logged out and logged back in as a different user.
I launched Eolie and Atril as the different user, and I had the same problem.
