Then I think this is a problem we never saw before. Unfortunately,
since I'm unable to reproduce this on my machine, I cannot debug it

libraries to their latest versions.

The profiles clearly tell the problem is related to font metrics, but
they don't tell what exactly causes the slow-down or why. Sorry.
