Bug Description
Binary package hint: emacs23
When scrolling through a text document or typing in the echo area, fonts often appear scrambled initially, with characters printed on top of each-other. After several seconds of inactivity, the display corrects itself, but the problem will reappear with additional scrolling or typing.
Observed:
- full screen and smaller window
- font-lock on and off
- monospaced and proportional fonts
- with current ~/.emacs file moved out of the way and no .Xdefaults or .Xresources to affect display

I am getting what appears to me to be a highly related bug. I get scrambled, overlapping fonts. In my case, this is not related to scrolling specifically, but occurs even while typing.
As a temporary work-around, I am forcing Emacs to redraw after every command (code below!). Emacs is now usable, although it causes a very unpleasant flicker.
