Bug 90789

*** Bug 93494 has been marked as a duplicate of this bug. ***

I have plans for making Option "TearFree" work for rotated outputs, but I don't know when I'll get around to it. Others are welcome to jump in.

If it helps a tear free desktop is easily the most desired option for me.

Add support for transforms to separate scanout buffer  infrastructure

Here's a preliminary patch for this, which should reduce tearing even without Option "TearFree" and eliminate it with the option enabled.

Note that for 90/270 degree rotation, you'll need to patch xserver with http://lists.x.org/archives/xorg-devel/2015-December/048377.html or to disable the HW cursor with Option "SWcursor".

Thank you much. If I'm not super familiar with patching my xserver/video 
driver where's the best place to get started? Would it be worth waiting 
until this gets included in fedora?

With https://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=798c4fd16d339b1ad5fd729cc884be084c60e38b (and xserver >= 1.16), Option "TearFree" eliminates tearing with rotation.
