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.

Comment 1 Kevin DeKorte 2010-10-10 07:46:04 UTC 
When running the driver that shows the problem, apps like gnome-shell do not display anything on the desktop. So this could be a blocker for installations using gnome-shell as the default.

You'll be hitting this clutter bug: http://bugzilla.clutter-project.org/show_bug.cgi?id=2228

When GLX_INTEL_swap_event is available clutter uses the events to drive the main clock, but doesn't actually select for them.  Mesa prior to 7.9 had a bug where it would send events out to all clients, even if they hadn't selected for those events, so this clutter bug was only exposed recently.
