Jumping up and down breaks blocks leaves break marks until you begin to break a different block.
How to reproduce
Find a tree, preferably a tall one.
Chop down all the logs hat you can reach.
Jump up and down to break the next block above. You should not be able to reach it, more so, break it.
By jumping up and down whilst holding left click, you should start to see the log breaking.
The break marks stay there even after leaving it half-broken, until you begin breaking a different block.
