Yes, the default settings for the games use antialiasing, and I'm using fbo's.
They have to be used because not using them causes games run at a crawl (2 to
13 FPS instead of 20 to 180 FPS for Half Life games). I should have specified
my video settings, but I've always thought opengl with fbo was the default for
all games. That what I've always used, and until this regression error it
always worked great.

I've been messing around with a lot of configurations and trying to get all my
regular suite of apps and games to work so I'm too tired to do another
recompile now. But I'll pull the latest git tomorrow and see if turning off all
anti aliasing works around the problem, but I would still think its something
that needs to be fixed because it can dramatically improve graphics quality,
and like I said always worked before this regression error.
