Using MPV OpenGL output for video on DRI2 with TearFree enabled, frames are sometimes displayed with desktop visible, outside of the fullscreen-scaled video image area (e.g. when for example 4:3 video is scaled to 16:9, padding left on left and right of the image).
This does not seem to occur with TearFree disabled, nor with DRI3 (TearFree enabled or not).
