Well, it's not just fonts, is it? The buffer starts one line high, even
when the fonts are tiny, and that last screenshot where two lines fills
the screen is supposedly 11pt. fonts.
Come to think of it I should also mention that it looks like that last
shot, briefly during startup. 

I also notice now, that startup seems slower than it ought to be.
Takes around 12 seconds, while -nw is ~1 sec.
Cpu maxes out for some seconds there as well.


Hm.. not my specialty, but playing around with strace...
# strace -c emacs

I figure a lot of those read errors must be from blocks like this.

Something about fonts..., but I have to work on that..

I have none of the those anywhere on the system.
You don't think I should try to narrow down where the cause might be a
bit more before I start reading docs? Seems to me I could read docs for
a week to cover the possible territory at this point.. :)

tried emacs -QD but no change.

emacs -fn lucidasans-24 looks more sensible during startup, but then
just the same behavior. Hm.. lucida is not an option in the "default
font" dialog, but is one of the hits in xlsfonts | grep -i sans.


Well, some new angles to work on anyway.

Thanks :)
