With 2.21.14 we've switched the default accelleration method to SNA instead of UXA. You didn't provide any information about your hardware and configuration.

Sorry, i have the NVidia GeForce GT 555M with the Bumblebee software and the nvidia driver 319.32 installed.

With the UXA accelleration and the version 2.21.14-1 my system works fine. It looks, that my graphic card is too old for the SNA accelleration.

You should also probably fill a bug upstream at https://bugs.freedesktop.org

Probably you hit some fallback to unoptimized code.
