No, this was definitely a bug.  Because text layout is expensive, the
text module caches the layout based on a cache key (see
text.Text.get_prop_tup).  We were using the renderer id, and lots of
other stuff, but not the dpi, in the cache key.  I just added the dpi,
so it should work correctly now, though I have done no tests.  Give
r6098  a whirl and let me know.
