Colors?  Or do you mean the character sets displayed?  The colors look
OK to me, but I see that you're not getting horizontal lines in the
prompt etc. in the second case.

Screen is apparently not switching the terminal into the alternate
character set mode when doing the line-drawing, but the termcap has
line-drawing characters defined.  I don't know why this would happen
from GDM/KDM and not from startx except that it must be some LC_* or
LANG -related environment variable that is set differently (or not
set at all) in one case or the other.  Try saving the output of
"typeset -x" to a file in each case and then compare the two files.

Looks like you're unintentionally constructing unicode combining
characters which vim isn't displaying properly ("real" width vs.
display width conflict).  How you're getting started into combining
characters in the first place I can't guess unless your delete or
backspace key is sending something odd.

Have you tried running zkbd?  It'll tell you when your backspace or
delete are not sending ctrl-h and ctrl-?.

Of course it's possible that vim is switching the terminal mode to
keypad transmit or another flavor, so what you type at zkbd would not
be representative of what vim sees, but it's worth a try.

Have you tried gvim to see if the problem exists there as well?  If
it does, see above about environment settings ...

Run zkbd and follow the instructions.  If you have trouble getting zkbd
to work, see http://www.zsh.org/mla/workers/2008/msg00370.html
