Phoronix: Intel Releases 2.19 X.Org Driver To Fix Bugs
The xf86-video-intel 2.19.0 DDX driver was released this week to provide more stability fixes for UXA acceleration as well as provide support for the Intel Ivy Bridge GT2 server chip...
Good timing. I just upgraded to the 2.18 driver on my netbook yesterday, and noticed that although it seems faster, it has massive stuttering issues, and often a portion of the screen isn't updating on time.
I'll have a look at it later, and see if it resolved those issues :-)
