Thanks for telling me this.  I tried with -dpi 100, and this does
in fact fix *both* problems.  Now the fonts are a good size, and
the GUI is fairly snappy.

I find it a little ironic that myth needs an incorrect dpi setting in
order to get things the correct size.  The point of telling X your
screen's dpi is so that applications can choose font sizes in a way
that makes them show up the right size...  Is this a bug lurking
somewhere, or a design decision I don't understand?
