So you should.  We have corrected a bug: you now get the size you ask for
and 12pt on such a small window will be too large.

DId you think to actually measure the sizes?  Might be interesting 
(although you may need to measure the window too).

The change is more likely to be

     o	X11() was only scaling its fonts to pointsize if the dpi
 	was within 0.5 of 100dpi.

in the BUGS list.

I happen to have 99.4 and 120 dpi screens, and I assure you the previous 
default of 75dpi fonts was way too small for the default 7" window.
