I have noticed some strange behavior when using an external monitor with my MacBook and DejaVu Sans Mono (or Panic Sans) with Terminal.app and TextMate.
If I launch these programs prior to plugging in an external monitor, when I plug in the monitor, the fonts appear like so.
However, if I plug in the monitor first, and then open the application, the fonts are displayed like this.
Is there some way to ensure that the bolder, clearer version is always displayed, regardless of when I plug in an external monitor?
Note: I have noticed this behavior on many different monitors, connected via both DVI and VGA.
