Me too. I was going to send an e-mail about it later, but since you've 
brought it up... I don't know enough about the relationships between the 
graphics systems to tell whether this is a configuration issue or a bug.

* Kernel 2.6.29 + KMS. Horizontal tears are constantly in the same two 
places on screen, as if it's synced but incorrectly. Note that with this 
config, I had to use xrandr to create and set a +vsync mode as DDC 
output in Xorg log shows all modes with -vsync.

* I haven't tried 2.6.29 without KMS.

* Kernel 2.6.27 and 2.6.28 (Ubuntu -generic kernels). Horizontal tears 
are in random places, as if it's not synced at all. In this config, DDC 
output showed some modes with +vsync, so I selected one.

Both configs are using:

* xf86-video-intel 6d345c49f693cc5cffaa00b94559d2afcb3a0864 2009-04-10
* libdrm 07646002c6835537c6ae44ef9b3f8480762279b8 2009-04-10
* i945GM

I also wonder if the performance regression(s) with i945 are affecting this?
