Did you get a chance to profile the EXA text rendering slowness? It
might be related to my recent changes allowing partial migration of
pixmap contents. They save migration overhead but may introduce region
calculation overhead in some situations. If this is confirmed to be the
problem here, there are some possible countermeasures for the latter.
