This bug was also reported as a potential bug in Emacs, but it may be a bug in screen, or both. In the Emacs bug-report list, I have reported it as:
bug #13590: 23.4; Cursor jumps around while typing
I'll quote a part of the description here, but only a part, because the overall description was written relevantly in Emacs. Note that I have an addendum to the original report, which basically says I forgot to mention I was using Emacs under screen, and that Emacs seems to work fine when not under screen (but I only did very limited testing).
So here is the quote:
---------
I am currently trying to disable "Smart Tabs" for Python.
I start with:
emacs -nw ~/aoeu.py
Right off the bat, if I try to type
def hello, world!
I get the following:
deo h!ll , world
with the initial "de" highlighted in Cyan, "o h" and "ll" in blue, and the rest in grey.
If I then type "M-x whitespace-mode", the text sometimes reappears as normal text.
Also, if I try to open a file, and type "C-x C-f" and then "~/.git[TAB]" (or something similar), the tab completion jumps back over the text--indeed, if I repeatedly backspace, I'll even backspace over the highlighed status line.
I don't think it's a problem with "python-mode", because I have had this problem before, when trying to edit "~/.gitconfig". Since I was working with a lot of colors, I suspected that the problem involved funny escape characters.
