--- Comment #8 from Michel Dänzer (michel at daenzer.net) ---
The tearing occurs because amdgpu doesn't support scatter/gather scanout with
Raven yet, so page flipping cannot be used.

For the time being, you can get rid of the tearing by enabling TearFree:

 xrandr --output eDP --set TearFree on

See the amdgpu (4) manpage for more information about TearFree.
