Hmmm, I've noticed that recent version of emacs have started flickering like
crazy in some circumstances, but haven't had much time to debug it.[*]

I mostly see this in Gnus *Summary ...* buffers: the whole (summary) window
will suddenly start flickering, and it seems that it's redrawing the entire
window constantly.

I don't know if this is connected with set-buffer-modified-p or not though.

Thanks,
