Glitchy Enderman.

Hello.
This glitch happens mostly when I turn on the fancy graphics but sometimes without it as well. the enderman himself looks fine but in front of him like half a block distance he creates very huge thin, long and tall black plates In V shape starting from the enderman and expending to the front of him. I wish I can get a screenshot describe it better! But weirdly it's not happening at this moment but it does often
