The slowdown is gone for me except in fullscreen HD videos (either VLC or flash - 720p+). I am quite sure this is a KWin bug because I tried downgrading to Mesa 8.0.4 (which was working fine before) and I experienced the same issues. So it is something in the 4.9.2 -> 4.9.3 transition (perhaps even the above patch).
I also noticed that low resolution videos (480p) play smoothly, as well as the HD videos but only when not viewed fullscreen.
