Re: unpleasant flickering in terminal emacs

[Amos Bird <amosbird@gmail.com>]

Hi Eli, "emacs -Q" works fine, same as my emacs's *scratch* buffer 
with 100K
lines of code. However, after switching to Fundamental mode and 
turning of
font-lock-mode, xdisp.c buffer still flickers while scrolling. All 
the minor
modes are the same as the *scratch* buffer. I've also tried 
loading the same
theme of "emacs -Q", it doesn't help either.
