Meteor had snaking issue too, as had Lockheed P-80:
Most did at that speed, however the Lockheed's issue seems to stem from its hydraulically boosted ailerons.

There is a good reason nobody else in the world used hydraulically boosted controls at the time.

Lockheed pushed them but it was well into the 1950's before they technology worked even close to what was intended.

Isn't 'snaking' a horizontal movement?

Another stability problem that was quite common in airplanes of the period around WW II was a tendency for a continuous small-amplitude lateral oscillation in straight and level flight. This problem was called "snaking" and its cause was quite mysterious.

The flying wings of the day all exhibited the "snaking" problem to an even greater degree.
