Hi Daniel,

This are my results:

1. OpenGL > "Sync To VBlank" = ON
Workarounds > "Force full screen redraw (buffer swap) on repaint" = ON
No tearing at all, but with this settings video playback is quite jittery and widow movement looks worst. It's very slow and windows lag behind mouse.

2. OpenGL > "Sync To VBlank" = OFF
Workarounds > "Force full screen redraw (buffer swap) on repaint" = ON
Heavy tearing in video playback, but widow movement is tear-free and faster than in previous setting (both ON)

3. OpenGL > "Sync To VBlank" = ON
Workarounds > "Force full screen redraw (buffer swap) on repaint" = OFF
Video playback is tears occasionally, window movement is similar to the previous setting

4. OpenGL > "Sync To VBlank" = OFF
Workarounds > "Force full screen redraw (buffer swap) on repaint" = OFF
Heavy tearing in video playback, window movement very fast but with tearing.

For me option 3 is least wrong of all.
