It is possible to move on ice blocks while crouching, in a direction up to 45 degrees away from the direction you should be moving based on the movement key you are pressing.
How to replicate: (this is shown in the video "Ice Sneaking Direction Glitch Take 3")
Build a flat surface of ice blocks. Stand in the centre, and face diagonally on the X/Z axis.
Move your crosshair to be just to the side of the exact diagonal between the X and Z axis (it doesn't matter which side). Your crosshair should not move from this point onwards.
Wiggle your player left and right, alternating directions a few times each second.
While still wiggling, crouch.
If the glitch has happened, you will notice your direction of movement has changed. You can stop wiggling, but stay crouched. Now if you attempt to sneak left or right, you should notice that your character moves straight along either the Z or X axis. This can be made easier to see by doing either (or both) of the following;
Switch to third person view. You should see your character's body (most noticeably their arms) shudders while you move during the glitch.
Build a flat surface of non-ice blocks connected to your ice surface, at the same level. Once you have begun the glitch, if you sneak off the ice and onto the non-ice blocks, you will notice your direction of movement changes back to what it should be.

Can you provide a short video of you reproducing the issue? From your description I was unable to reproduce.
Done.
As you can see, when I sneak along, pressing only a or d, I go parallel to the blocks rather than diagonally. Then when I step onto the netherack, my direction changes to what it should be and I start moving diagonally.
Is this still an issue in 1.16.4?
Yes, and I found an easier way to replicate it. I'll attach a new video later today.

Thank you!
Hm, I'm having trouble with that one. I attached my video, am I doing it wrong there?
Your wiggles when crouching should be shorter (change direction with the same frequency as before crouching). Also, your horizontal mouse movement (which you may need to attempt a few times until the glitch happens) should be a bit longer. The purpose of this movement is to change the direction you are facing to be nearly (but not exactly) in line with the axis, so assuming you start facing perfectly diagonal, the change in the direction you are facing because of this movement can be up to 40 degrees.
I hope this helps 🙂
I found an even easier way of doing it! Video uploaded (named "Ice Sneaking Direction Glitch Take 3") 🙂
I could change the description of this bug to reflect my current understanding of it (and to better describe the bug), but I thought I'd ask if that's what you want here first. Should I update the description?
Thank you! I finally got it to happen! Feel free to update the description if you want
Done! This was fun 🙂
Affects 24w21b
The information by @unknown is still noteworthy though (could simply duplicate that issue, or have a 'caused by' relation added if the issue should stay seperate).
this was fixed in 25w02a
Whoops, I resolved the wrong ticket by accident. Disregard fix version 19w35a.
