MCPE 15.0 Particle Massive Lag Bug

Whenever I am in a chest or furnace, particles build up and when I exit the chest, they are all displayed at once and i am swarmed in lag. This works with nether portals, fire, status effects like poison or hunger, and the most annoying one is RAIN. I can literally not open ANYTHING while it's raining in fear of lag. Crafting tables seem to be fine but furnaces and chests are a bomb waiting to go off. The longer it's open, the worse it gets when you close it. PLEASE FIX THIS MOJANG!!!
