<pre>Exactly the same problem here. Tearing starting from upper left corner, in a
45% angle and then horizontally somewhere in the 1/3 upper part of the screen.
Clearly some attempt at VSync is being made cause the lower half of the screen
is always perfectly smooth.
OS: Ubuntu Gnome 16.04
Radeon HD 6320
Using radeon driver from Oibaf PPA (package named xserver-xorg-video-radeon,
version: 1:7.8.99+git1612191933.720dd0~gd~x)
It's not just a video playback problem, in Gnome (Mutter compositor) the
tearing applies to the entire screen, so it also occurs when dragging a window.
There is no tearing when starting a 'Gnome on Wayland' session. Also no tearing
when running Kodi in Wayland (through XWayland, which works surprisingly well).
I'm using almost the same configuration as tobias.brunn:
20-radeon.conf
Section "Device"
Identifier "Radeon"
Driver "radeon"
Option "DRI" "3"
Option "TearFree" "on"
EndSection
Removing options DRI3 and TearFree makes no difference.</pre>
