This seems to be a McCLIM Freetype problem that causes some strings to
be printed one pixel to the left of where the stream cursor is
actually positioned. Goatee doesn't suffer from this problem because
it ignores text styles, but in Drei, the input will walk a pixel to
the left for every redisplay. I think this problem is font-dependent,
as I could only get it to show up with a :sans-serif font. This
Listener session sort of shows the problem (notice that the output
records have different positions based on which string is printed - I
guess the variable-width and anti-aliasing stuff causes it):
