Here I also remember DuckDuckGo being sluggish for a while, but the
thing seems to have solved itself.

I am running Xorg server version 1.16.0, so I suspect the Intel video
driver can be a better guess, because the Intel driver and mesa got
several updates for me in the last weeks. I am using version 2.99.916,
so the issue must be somewhere in the versions of the Intel driver in
between versions 2.99.910 and 2.99.916
As a recap, we have the following versions tested:
Xorg Intel driver Slowness?
======== ============= =========
1.15 2.99.910 No
1.16 2.99.914 Yes
1.16 2.99.916 No
If this is a problem caused by the driver, probably it won't be worth
it to provide a workaround in WebKitGTK (and JFTR, it may not be even
possible to workaround).
