        <pre>From time to time I can notice the flickering (tilting) of entire screen. This
happened on Windows also untill Catalyst beta9 driver came out. One of the
fixes in the changelog was:

Feature Highlights of The AMD Catalyst 13.11 Beta9.5 Driver for Windows:

Resolves intermittent flickering seen on some AMD Radeon R9 270x graphics cards

Now this is fixed on Windows, but I have the same problem still on Linux (Arch
Linux).

kernel: Linux silverstone 3.13.0-rc5-MAINLINE #1 SMP PREEMPT Mon Dec 23
00:19:39 CET 2013 x86_64 GNU/Linux

glamor and xf86-video-ati are the latest git snapshots.

Could we contact Catalyst developers and get some more info on this. I don't
see any log warnings (journalctl -b, xorg.log etc), but I can provide them if
needed.

Thanks!</pre>
