movement input lag

I do not know if it is just due to snapshots being 'experimental' and generally having lag issues, but as of today I have noticed that movement is a little bugged. However, it is not the normal lag, such as an input delay, but rather the movement continuing for longer than expected.

Scenario: Holding down W to move forward, then releasing W.
Result: Movement continues for much longer than intended, and will not accept any other keys pressed until movement stops.
