Getting the font size right has been a bit problematic on several
platforms.

It usually is because of a discrepance of the size of fonts as
demanded from the display engine and the actual size displayed.

In short: it is possible that preview-latex obeys the demanded font
size, while nobody else does.

If you select other fonts for the buffer and regenerate, is
preview-latex always "wrong" in the same manner?  In that case the
geometry might be off-kilter.

Most other packages won't be nearly as sensitive to that.

I don't think it gets better on any other machine.  On Emacs-21, we
have used colored transparent frames in the image in order to avoid
ugly blinking, and this also affects the mouse highlighting.  It has
other drawbacks, and the cursor flashing problem is no longer there in
Emacs-22, so we don't do the the frames.  If you think this important,
you should probably ask on emacs-devel whether it is possible to make
mouse-highlight on images work similar to cursor on images.

I don't think that is the problem: rather the tooltip should contain
two lines.  I don't know what happened to the second one.  Maybe the
toolkit is not happy because of \n instead of \r\n or something
similarly obtuse?
