I was testing clutter based apps on my machine using the r600g driver. I had
installed kernel-2.6.36-0.35.rc7.git0.fc13.x86_64, libdrm-2.4.22-1.fc13.x86_64,
mesa from git, and xf86-video-ati from git. All my 3D based apps worked except
those that were clutter based, no clutter actors would draw on the screen. I
rolled back to the Fedora 13 drivers and found that the clutter apps worked. I
upgraded mesa back to git and found that clutter apps still worked, I then
upgraded the radeon driver and found that it did not work. I rebuilt
xorg-x11-drv-ati-6.13.1-0.4.20100705git37b348059.fc14.src.rpm for Fedora 13 and
found that it failed.

I then did a git bisect in xf86-video-ati between 

ad999e633ff41d27eed9d2c6535e163a7181b0bd        6.13.1

and 

fb7911912e60b2cdbc2152b96847775b767ca3ef        6.13.0

when I completed the bisect it told me this.

    kms: add support for the MSC swap & sync API

    This patch is mostly a port over of Intel ddx code for
    MSC support. It needs a radeon KMS module with version
    2.4 which has the query for hw crtc id.
