changing a second time)

Sorry, I couldn't reproduce it. I can't perform the step "once gnome-font-viewer
is running, start gnome-font-properties, then choose
advanced and change hinting 2 times (wait until display is refresh before
changing a second time)"

Could someone please tell me where the Advanced button is?

I managed to trigger this bug too, and it seems to be an Xft bug.

The bug report and patch are available here:
  https://bugs.freedesktop.org/show_bug.cgi?id=1951

It turned out to be a simple operator precedence problem.  You might want to
apply the patch to your copy of Xft while waiting for it to be applied.
