23.0.60; Bold screen fonts have been unbolded

[David Kastrup <dak@gnu.org>]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

This is pretty weird: I don't replace my Emacs that often, so I am not
sure when this started: some place in the last months.  The effect I see
is that bold (and strong-colored) fonts don't appear bold or
strong-colored but with normal stroke width and somewhat dulled.

The crazy thing is that while I drag the frame around on the desktop
(which I would have thought used image copy operations), the fonts
appear properly fattened and colored.  When the movement stops, they
immediately (without releasing the mouse button or anything else) become
normal weight and thin-colored again.

Does the version info provide a clue?  Do others see this effect as
well?  For what it's worth: I have an ATI graphics card in the laptop
and that has produced some other artifacts at times, so there is a
possibility of a driver problem, but I somewhat doubt it.
