The Xv output produced by the radeon driver (6.14.4) in Debian wheezy appears
to be not vsynced on my Radeon HD 4670; tearing shows up.
xvattr says that XV_VSYNC is 1. Using mplayer to play a video with its gl
output option is properly vsynced, as are other OpenGL-using apps. When using
the xv output option, tearing occurs.
Attaching ~/.drirc (vsync enabled), output of xvattr and xvinfo (XV_VSYNC 1),
and Xorg.0.log.
Attaching make_flasher.sh, a script using mencoder and ImageMagick to generate
a flashing avi to make the effect particularly obvious. Playing this avi with
"mplayer -vo xv build/output.avi" produces tearing, whereas "mplayer -vo gl
build/output.avi" does not.</pre>
