I noticed something weird with the new Oz disc. Whenever there is a background that is blurry (in closeups), the frame in the background moves around, almost warped. Check out the Wicked Witch's closeups in Munchkinland. The background on the right is breaking apart and moving. Is this a mistake from the restoration, where each section of the frame was repaired? I didn't notice it on my other Oz discs.
