It is FVWM virtual desktop. I don't know how to put it better. To further narrow down the issue: when the GUI frame is hidden behind another window then exposed, sometimes it exhibits the same symptom. This redisplay issue only happens in a recent version of emacs. I don't recall encountering it for instance half a year ago. > >> the entire frame shows only the background color, no letter >> or only part of the frame is visible.

A `default' frame started with emacs -Q has the same redisplay problem. Yuan
