Two things in this bug report: 1) Large font sizes result in corrupted glyphs. That is, parts of the glyphs will be missing, or whole glyphs will be missing. In Firefox, selecting the text sometimes helps show some of the missing parts, while often causing new parts to disappear. 2) KDE 4 applications show completely missing glyphs with normal font sizes. Both problems exist with EXA. They go away with XAA.

Please attach (as opposed to paste) the full Xorg.0.log as well. Does it also happen without Option "AGPFastWrite" and/or "AccelDFS"?

Any combination of options with EXA seems to produce the same behavior: messed up or missing glyphs. Granted, I haven't tried the full Cartesian product, but I did try what you suggested, and a few other things (like MigrationHeuristic) and I still get the same behavior. Only switching back to XAA fixes it.

turning the following option off made the trick to get the font back to normal. Option "RenderAccel" "off" The Other option had no effect at all.
The latest git xserver seems to fix this issue. I'm guessing it's related to commit 21c116219cd5c6845a0955f2d88fdb5fab5c17cf which addresses something that sounds very similar to this.
