I discovered the reason behind this problem. In my home, I often use my
netbook (the machine running GNU Emacs 23.4) connected to a big external
display by VGA output. Today, I used the LVDS screen and guess you what
happened? The problem disappeared. This seems consistent with the problem only
showing up under X frames of Emacs. I'm now wondering why it's
happening only when I connect to the external screen. The only thing I
could think is the stretch transformation rule that I have configured by
xrandr as follow:
xrandr --output LVDS1 --mode 1024x600 --auto --output VGA1 --mode 1024x768
--scale 1x0.78125 --auto
Any idea? It could be a bug in Emacs?
