so the solution I found is to create a radeon.conf file in /etc/X11/xorg.conf :
Section "Device"
Identifier "Radeon"
Driver "radeon"
Option "TearFree" "on"
Option "DRI" "3"
Option "AccelMethod" "glamor"
EndSection
I have a suggestion : you should enable by default "TearFree on" if the graphic
card supports both DRI 3 and glamor,
it will permit to eliminate tearing even if vsync is set to "never" in kwin</pre>
