            Bug ID: 90789
           Summary: Vsync doesn't work for rotated display
           Product: xorg
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium

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.
