Describe the bug
using cells generates quite a lot of lag, so i installed optifine, which got rid of the lag...
but now, cell gates flicker on and off whenever a redstone signal is applied in the same chunk. none of the settings on optifine seem to change anything, and using different mods such as Foamfix and Vanilla fix generate the exact same issue. this is purely graphics wise, but looks really odd. flickering happens even upstreams, were signals shouldt travel to.

To Reproduce
Steps to reproduce the behavior:

1. install project red
   2: install optifine
   3: make something with cells, such as a decoder or a multiplexer
   4: flick the signals... the gates will flicker on and off

Expected behavior
gates should ust stay normal, and their state shouldt flicker
