Creative 1 ( I believe all creatives )

Detailed description of bug:
Whenever I start building, everything is fine. After I place a couple of blocks down really fast, my blocks start lagging, and whenever I right-click to place down the block, it disappears immediately after. I have to place the block down about 3 times for it to finally load in. It's been happening to a few of my friends, as well. It isn't my client, I'm using optifine, and when I switch back to 1.10 or 1.9, it still glitches.

 

Figured it out.
