It seems there is a problem with powersafe:

With auto:
echo auto > /sys/class/drm/card0/device/power_dpm_force_performance_level

you will see heavy screen flickering on higher display resolutions (2560 x
1440). It's ok with 1920x1200.

With low or high:
echo low > /sys/class/drm/card0/device/power_dpm_force_performance_level or
echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level

there is no screen flickering with all display resolutions.

hardware:

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Curacao XT / Trinidad XT [Radeon R7 370 / R9 270X/370X]

Kernel: mainline 4.7.0-rc7 

Drivers:
x11-drivers/xf86-video-ati-7.7.0
media-libs/mesa-12.0.1 (with radeon and radeonsi enabled)
x11-base/xorg-server-1.18.3
