This is not, strictly speaking, a bug. It will be a bug soon, though.
Read on for details.
There are no 11pt fonts for TeX. TeX uses a \magstep, which is to say
that all ``standard'' TeX font sizes are of the form
(n/2)
10 * 1.2
where n is some whole number. Thus, the standard sizes are 10, 10.96, 12,
and so on. The upshot is that ``11pt'' in LaTeX is really 10.96pt, giving
a dpi of 300*10.96=329, instead of 330.
Once the DVI standards committee report is published (TUGboat 11(4)), the
behaviour of xdvi will become a bug. Right now, there are no requirements
for DVI drivers (of which xdvi is one). The proposed standard for a Level
0 driver will specify a font-faking scheme, under which a 4% error margin
is required. Thus, cmr10.329pk would be considered an acceptable replace-
ment for cmr10.330pk, which it presently is not.
When I get my act together and supply PS-like pk files, they will appear
in both sizes. (Actually, there'll probably be a link :-)
Hope this rambling made some sense!
