--- Comment #2 from Pierre Ossman <ossman at cendio.se> ---
That was the diagnosis in the Red Hat bug linked above, given the various tests with pango and cairo. Especially the last test, where a special build of cairo without subpixel positioning got rid of the issue.

Could it be that subpixel positioning is the new default in cairo, and WebKit needs to do something explicit to turn it off?

That merge request for GTK shows some extra cairo calls. Could those be relevant for WebKit?
