I upgraded to xf86-video-ati-.6.13.0 and after restarting X I noticed high cpu usage (~30% instead of 8%) due to X. I downgraded xf86-video-ati to version 6.12.5 and cpu usage is now normal (~8%). Reproducible: Always

Created attachment 237485 [details] emerge --info output
x11-base/xorg-server-1.7.6 is installed with these use flags: USE="nptl sdl xorg -debug -dmx -hal -ipv6 -kdrive -minimal -tslib" I haven't tested yet if problem occurs with other xorg-version or with other xf86-video-ati version
Do you still see this with xf86-video-ati-6.13.1?
Please get back to us. Thanks
