Multiplayer bug: Green animated XP "fire-fly" distorts vision

Sometimes when picking up experience, the "picking up experience"-animation plays over and over, buzzing around in front of you face like an annoying fire-fly, distorting your vision entirely :/

There seems to be no sure way to clear the problem - often you need to log off and on again to clear it. In rare cases though the glitch suddently disapperars by itself.

I've only observed the bug on clients in mulitiplayer. The bug happens on iOS or Windows 10 devices both (haven't tried Android).

The bug only happens sometimes when picking up experience in confined spaces, ie. when mining coal in a 2x2 mineshaft and picking up the experience.

To reproduce:

• Start up MCPE 0.12.3 on Windows 10

• Connect to the session from other 0.12.3 client, either iOS or Windows 10

• Mine something which provides experience (ie. coal) in a confined space (like 2x2 or 1x2 tunnel).

The bug doesn't occur every time you pick up XP. Sometimes you can mine for minutes before it happes, other times it happens the first time you pick up the XP
