Just installed fedora 22 on my desktop and I have a dual monitor setup. The main monitor is landscape and works fine the second is portrait and it seems like vsync is not enabled. When I scroll through text on the portrait monitor there is a line of tearing that occurs (which migrates across the screen). If I switch the monitor back to landscape the tearing does not occur. If it matters the landscape monitor is connected on DVI while the portrait is on displayport. Video card is a radeon 260x. Rotation was done via gnome 3.16 setting panel.

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.

Created attachment 120682 [details] [review] 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".
Created attachment 120703 [details] attachment-12541-0.html 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?
