In the above video is a machine that does a relative teleport of the player every 100ms (2 ticks), alternating between 1,0,0 and -1,0,0. As can be seen, this is mostly seamless but occasionally snaps the player back quite a bit. Though it's not in the video, sometimes the player also gets "stuck" where they can't move or turn their head because they are getting snapped back constantly, much more rapidly than the teleports. I have slowed the machine down to one second between teleports and am still having this problem.
Note that this happens both in single player and on a multiplayer server running locally. The server is having no trouble keeping up with real time, and there is nothing in the console aside from the output from the command blocks.
UPDATE: I notice that if the player is crouched when they teleport, their view angles are reset to zero and they will uncrouch, 100% of the time. This may or may not be related.

Is this still a concern in the current Minecraft version 1.7.9 / Launcher version 1.3.11 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

It is not a concern in Minecraft 1.7.9 as it has something to do with the "smooth relative teleportation" introduced in one of the 1.8 snapshots, but it is still a concern in 14w11b.

This is still a bug in 14w20b.
Last Username, please update the affected versions list to help Mojang.

Confirmed,
this even happens when the player is moving really fast and you only have one tp command

The exact bug in the description may be fixed, but I can still confirm a similar bug. Perhaps MC-76463 should be reopened as a separate ticket?

Done.

Still in 1.11, go on a server or a realm and put in a repeating command block /tp @p ~ ~ ~ and move around. You will occasionally be teleported back. Spent 4 months figuring out what was wrong with my map but found out a month ago 😛

@unknown: Is your issue MC-76463 ?

Kumasasa, I think this is the same thing as MC-76463 If I'm correct.
It happens to me as well, though it only appears to happen when you teleport at high speeds, or even a low speed. Dropping yourself through the teleportation hole whilst one or two blocks above won't cause teleporting issues.
