Hoping my attached gif will properly animate.
(In the GIF, you will see I aligned "CPU:" with the horizontal line of the ripe crop. I then didn't touch the mouse and took many screenshots. I was in a much more violent vibrating state than the GIF shows. The GIF also shows how sometimes I slip into the block.)
Problem still happens for 16w33a.
WIndows 10 Pro
Java 1.8.0_101-b13
In the case of the attachment above, I got stuck for a slightly different reason, yet the same. I was simply farming potatoes when suddenly I got stuck.
It's the same issue in that it seems I got stuck when the surface I was on changed state. Originally it became dirt when standing on it and getting stuck, but by the time I started started taking screenshots for the animation, it turned green (that's why I'm standing stuck on green and not dirt that I just farmed potatoe from).
To repeat myself,
when looking at the GIF, look at "CPU:" in the top center of the screen.
From here you can more clearly see me bouncing by a couple of pixels before slipping into the block (was not touching the mouse). Even though I took many screenshots to take the GIF, it doesn't represent how violent the up-down motion of a few pixels is. It is extremely violent. Very very bouncy.
but i can't make this !
