The tearing continues after reaching the lock screen and logging in. The tearing is nearly constant, stopping only for certain actions like using the mouse or typing. The screen tearing can be "fixed" by issuing i915.enable_rc6=0 in the boot parameter. However, this is a false fix as it turns off important power management functions and, as a consequence, the fan runs constantly and on high.
