Bug ID: 89198
Summary: Setting Refresh Rate on monitor causes
flickering/artifacting
Product: xorg
Version: 7.5 (2009.10)
Hardware: Other
OS: Linux (All)
Status: NEW
Severity: minor
Priority: medium
Component: Driver/Radeon
Assignee: [email protected]
Reporter: [email protected]
QA Contact: [email protected]
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.
