It's not really anyone's fault, per se. The 1.9.0 server probably just hits a different path that isn't accelerated in the nvidia driver. Anything could cause this, but it's probably related to a memory format change. I even remember reading something a while back about using glyph atlases that might be related and could potentially be problematic to resolve.

The responsibility for fixing it is definitely nvidia's, though--it's up to them to find where it's falling back to software and hook the acceleration back up.
