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.
