--- Comment #3 from zhixinx.liu <zhixinx.liu at intel.com> ---
sorry, i have not much background knowledge about X

you said:
>>Try a few other compositing managers.
    as my description, firefox/mplayer can also reproduce your step 1 and 3.

>>1. Confirm it works with bare X.
>>2. Try compiling xf86-video-intel with --enable-tear-free and use bare X.
>>3. Confirm it fails with gnome-session
>>4. Try xcompmgr
>>Now try rendercheck -t blend,composite -f a8r8g8b8 in the 4 different modes.

your step 4: try xcompmgr, you mean that=>first start X, then start xcompmgr,
after that, check output?

about command "composite -f a8r8g8b8", how could i get command "composite".
log:
[root at x-bdwmedia ~]# composite -f a8r8g8b8
bash: composite: command not found...
[root at x-bdwmedia ~]# yum install composite
Loaded plugins: langpacks, refresh-packagekit
No package composite available.
Error: Nothing to do
