MaJoR, I'm not able to create a bug report at the moment due to Google code giving server error (500 code) responses right now. I can later though hopefully.
I am using the GeForce GTX 750 Ti running driver 347.88
The only AA options presented to me are "4x SSAA", "FXAA" via post processing, and an generic "2x/4x/8x AA" (is that the MSAA?). Generic 4x AA and FXAA have no issues. It is only 4x SSAA that has the problems on build 4.0-1609 and newer.
I can also confirm that the issue only happens when using > 1x internal resolution (so it does not happen at 1x). I am using "auto multiple" so I'm not sure the exact factor, but I imagine its using 2x since my screen is 1080p.

Just to be sure, you didn't compare SSAA vs CSAA, did you?
