Sorry, originally metioned here https://bugs.freedesktop.org/show_bug.cgi?id=91721#c9. However it happens also in vlc.

Tried vlc with TearFree on/off, vlc is itself just plain broken (libva errors) on my Fedora test box, mplayer works fine.

Mplayer/mpv works fine for me too. I belive, it's related to on screen controls.
