[h-e-w] ClearType in Windows XP: Dirty Cursor

[Bill Baker]

Noble Emacs Gurus,

I have been experiencing a display bug in Emacs NT, version 21.1, that
appears in Windows XP when ClearType is enabled.  It has two manifestations:
one minor, and one major.

  Minor bug: the leftmost and rightmost pixel columns of
  each character can get a little munged.  Still readable,
  but munged nonetheless.

  Major bug: when in MMM mode in a region that is colored
  differently than the main page color, typing leaves vertical
  bars between characters, making it extremely difficult
  to read what has just been typed without a forced screen
  redraw.

Both problems go away each time the screen is redrawn (C-l).

I can send screen captures of the problems on request.

Many thanks,
Bill Baker
