I have backing store support enabled (but only a window or two with that
style forced), and since I've turned it on, I've noticed that the root
window will not always be redrawn when switching from the console to
X--I'm voting for the X bug theory.

XFree86 version: 4.2.1
screen #0:
   options: backing-store YES, save-unders YES

fvwm 2.5.4 (from cvs) compiled on Oct 21 2002 at 22:33:57
with support for: ReadLine, XPM, PNG, GNOME WM hints, EWMH hints, Shape,
SM, Xinerama, XFT

(but I think the fvwm version is irrelevant)
