I don't think they are one and the same. They are definitely similar but in MC-69865 he doesn't seem to be trying to break a different block. In my case I am breaking wheat and then the dirt. I basically alternate between placing wheat seeds and then breaking 2 seperate block entities.
Edit: The video is compressed in H265 so might be why you can't view it. I'd recommend downloading the file then opening it in VLC or something that supports H265
Hello Anthony,
My specific case of this bug is most likely not affected by Optifine. As Tail commented 3 days ago (for example: MC-157404), there are similar cases where players have experienced the same issue. I'd be fine if this would be marked as duplicate as there are a reasonable amount of them when opening the MC-157404 ticket where the issue is described.
