The Xorg driver decides which CRTC to synchronize with based on the
window geometry. For a window with no visible geometry, it may choose a
different CRTC than for the visible output window. In the case of DRI3,
the Xorg Present extension code may even fall back to the fake CRTC in
that case, which only generates a fake vblank event once every second.
