            Bug ID: 89198
           Summary: Setting Refresh Rate on monitor causes
           Product: xorg
           Version: 7.5 (2009.10)
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: minor
          Priority: medium
         Component: Driver/Radeon

Setting the refresh rate of an ASUS VG248QE to 144Hz causes
flickering/artifacting in various Desktop Environments, including KDE, XFCE and
Cinnamon. This occurs with compositing on and off in XFCE and Cinnamon (have
not tried compositing off in KDE). If I set the refresh rate to 120hz the
artifiacting goes away. On windows 7 there is no artificating when set to 144hz
so it is not a hardware issue. I have used the GUI tools available in XFCE and
KDE to change the refresh rate, and lxrandr on Cinnamon.

I am using mesa 10.4.4 (incase that helps) and xf86-video-ati 1.7.5 I am also
on Arch Linux. If you would like any log files I will be more than ready to
provide you with them, ATM I have no clue what is useful.
