When "ClearType" method is selected as the "method to smooth edges of
screen fonts" (in Display Properties, Appearance tab, under
"Effects"), there are various problems related to display of
-characters: 2-pixel trace is left behind when moving overlays, bold
-fonts can be hard to read, small portions of some characters could
-appear chopped, etc. This happens because, under ClearType,
-characters are drawn outside their advertised bounding box. Emacs 21
-disabled the use of ClearType, whereas Emacs 22 allows it and has some
-code to enlarge the width of the bounding box. Apparently, this
-display feature needs more changes to get it 100% right. A workaround
-is to disable ClearType.

There are problems with display if mouse-tracking is enabled and the
mouse is moved off a frame, over another frame then back over the first
