Xorg.0.log
While running various Unity engine games (tested with the cursor is drawn
slightly offset to the bottom-right of the real position observed by
applications. It does not matter whether the cursor is over the game's window
or if it has focus or is fullscreen / windowed / iconified.
I have bisected this to the following change in xf86-video-ati:
commit ddaba449e8d6fe9fc0d97085e4045843fd8d7af9

Disable CRTCs when disabling the outputs
When turning the outputs off (DPMSModeOff), CRTCs stayed enabled. This led
to higher gpu temperatures than with fglrx driver.
v2: when entering DPMS also disable active CRTCs
v3: use drmmode_set_mode_major() for enabling CRTCs when leaving DPMS
