From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> With vrr enabled the hardware no longer latches the registers automagically at vblank start. The point at which it will do the latching even when no push has been sent is the vmax decision boundary. That is the thing we need to evade to avoid our register latching to get split between two frames.
