In TL 2003 (i386-linux), the following brings up the X window, but it is
blank, no dot is displayed:
  $ mf  # same result with mfw
  This is METAFONT, Version 2.71828 (Web2C 7.5.2)

After a second
the dot shows up.

Furthermore, with this sequence, the dot is (correctly) displayed immediately:
  $ mf
  This is METAFONT, ...

Can someone test this with the current binaries?  If it's still
happening, it should be straightforward to fix.  It's not the first time
there have been sync problems like this in the display code, I remember
well and to my sorrow.

(Unfortunately I don't currently have a practical way to test
interactive X display stuff with the dev sources.)
