Hi Chris,
thanks for your answer.
I will try the latest intel driver, but in case it helps or you get an idea, I found that it has to do with the Antialiasing settings:
I am using an OTF font (Lucida Sans OT Regular) with cinnamon. Sometimes when I wake the computer up from suspend to ram the fonts are gone.
*BUT*: Switching from (in Font Settings of Cinnamon settings) Antialiasing: Grayscale *away* fixes the problem.
WIth Antialiasing: Rgba or None the fonts remain stable as far as I can see, while with Grayscale they are disappearing.
In fact I can turn the fonts off and on without a problem by simply swithcing the antialiasing.
Maybe this rings a bell at someone.
Thanks
Norbert

Currently my font displays some kind of strange symbols instead of an m ... looks a bit like a Kanji.
I remember a similar bug around 2.99.917 but that tag is over a year old now and there have been many bug fixes since. You'll need to verify you can still reproduce your issue with the latest from git://anongit.freedesktop.org/xorg/driver/xf86-video-intel and if so do a bisect from the previous working kernel or xf86-video-intel to identify the problematic commit.
