Are you using bitmap fonts?
Or do you have antialiasing off for the fonts in use?

This is one case where the PrepareAccess path would be faster because it is
write-only access.

Unfortunately, PrepareAccess doesn't know whether access will be write-only.

And this kind of write-only access is a bit different from what EXA normally
considers write-only.  EXA normally only considers an operation write-only if a
whole region will be written.  Here the glyphs are written but I assume the
pixels in-between are not touched.
