The bug
Sometimes, when you hit a minecart, boat, item frame, painting, or armor stand in Creative mode, the block behind it is broken as if the attack phased through the entity. The said entity still disappears as normal.
How to reproduce
Summon said entities and punch them in Creative (make sure you're not holding a sword). The block behind the entity should occasionally break as well.

Cannot confirm.
Are you sure your mouse button isn't bouncing ?
Sonicwave
Still reproducible in 1.8.1-pre3. It doesn't seem to be caused by bouncing since this does not affect mobs or blocks. However this definitely seems to happen less on my fast PC than on my laptop (attached results).

Re-tested and confirmed when utilizing the CPU

Confirmed for 1.8.1. It is easier to reproduce when moving mouse quickly to another block. I thought this was because of problem of my hardware before seeing this.

Place a Minecart on a rail, reopen the world and punch the Minecart and you will see that you destroyed the rail as well.

Please link to this comment in the description
The following is based on a decompiled version of Minecraft 1.9 using MCP 9.24 beta.
The reason for this might be that the method net.minecraft.client.Minecraft.sendClickBlockToController(boolean) breaks the block and one tick after that the entity is destroyed.

Note that this seems to only occur if you hold the left mouse button long enough. If you press left click very briefly, this doesn’t seem to happen.

I got this happening when I didn't hold down left click at all. It was instantaneous.
Relates to MC-215426.

Seems for me, that every 4-6th breaking of a painting does break the block behind it.
I don't know why.
