I remember the other day someone on this list. Having a very similar
issue as described above. Eli mentioned something about his graphic
card. But. It happens to me, when I have mesa-git with glamor
enabled. Whet I create an
emacs lucid frame and move to the scratch buffer and I write the
character 'w' (and also other identified characters but 'w' is the worst
case) that character is duplicated and also emacs lags for a few
seconds. It happens also with emacs23. On those cases I fire up qemacs or
xemacs or sxemacs those do not have the same issue.

Best Regards
