Ah, jumped to a conclusion as the kernel log seemed familiar.

This should fix it:

    sna: Pass desired CRTC viewport for completing single CRTC flips

    We cannot simply compare against the crtc->shadow_bo for all our needs,
    so pass in exactly the setup we want and apply that. In particular this
    is required when flipping away from the single CRTC setup on secondary
    pipes.

    Fixes TearFree multi-monitor regression from
