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? -- Bruno Félix Rezende Ribeiro (oitofelix) Ps: Please, let me know my english errors
