I've done a bisect and I ended up with:

sna/glyphs: Fix computation of extents for long strings
And make sure we consider such overflowing strings for correct clipping
To offset the cost of doing a full extents check (~10% on aa10text), we
introduce an approximate extents query (~1% on aa10text). The disparity
should be rare, and should be an overestimate to force redundant

Unfortunately, the commit doesn't revert cleanly and looks a bit too complex for me to start hacking out. However, I
have confirmed that a driver built from a tarball up to and including the preceding does not have the problem, whereas
one built from the tarball that includes up to and including this commit does.
Let me know if I can test a patch, but please cc me as I'm not subscribed to the list.
