This also happens in the current version...

I had a similar problem on Win7 64 bit - all fonts barely legible or not legible at all. I tried many things, then I FINALLY found the cure for this problem (on my setup anyway). In the advanced video settings (I had originally let the autodetect settings configure the graphics settings) I had to change the aspect ratio to one which is not normally associated with the screen resolution I was using. Cleared EVERYTHING up immediately! Didn't even have to restart...
No guarantee it would work for anyone else , but you might try playing with these settings a bit.
