vsync fullscreen problem on ATI video card

i have a problem with my ATI video card. On some programs, like mpv and vice, fullscreen doesn't work good: video is dirty and jerky.

$ mpv Labyrinth\ \(1986\).mp4 
Playing: Labyrinth (1986).mp4
 (+) Video --vid=1 (*) (h264 720x306 23.976fps)
 (+) Audio --aid=1 --alang=und (*) (aac 2ch 48000Hz)
AO: [alsa] 48000Hz stereo 2ch float
VO: [opengl] 720x306 yuv420p
AV: 00:23:07 / 01:41:03 (22%) A-V:  0.000 Cache: 10s+73MB

Exiting... (Quit)

(strangely with SMtube+mpv video is good.)

$ lspci |grep -i VGA
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV370 [Radeon X300/X550/X1050 Series]

if i remove vsync with this ~/.drirc:

$ cat .drircZ
    <device screen="0" driver="dri2">
        <application name="Default">
            <option name="vblank_mode" value="0" />
    <!-- Other devices ... -->

it works perfectly, but i need vsync.

i have no DE, only openbox.
on chromium video fullscreen on youtube works good.
