Hey, so I decided to pick up pixelmon and start playing it again today. So far has been fun, but after around 10 minutes of play my world starts flashing (turning chunks invisible and the reappearing in a fast succession. I have been trying all day to find a fix for this, whether it be through google searching answers to messing with optifine and even trying out different JMV arguments. (I was originally crashing too, but I fixed this through messing with my JMV arguments, so the crashing was just me.) Though I am almost completely sure that these chunk visual glitches are not just me and are at the fault of the mod as I have never had these issues in vanilla (even with some mods like optifine or PvP enchancement mods such as ones that keep your sprint on or let you have block hitting animations from 1.7 in 1.8) or any other modpacks I have played. For instance I could go load up a 1.7 modpack with 175 mods and not have this issue and same with 1.10.2 modpacks. I have also never had this issue in past versions or even in the beta periods of these past versions and I have also already tried the both new offical releases (5.0.0 & 4.3.0).
Below is generally what my world looks like, but in this picture it's just stand alone invisible because it would be pretty near impossible to capture an on going event in a single frame
Thanks!

Here is another example of it happening

It would let me select it for the attachments from my pc, so I uploaded it to gyazo, a picture sharing website.

I can and have reproduced this in vanilla and forge only environments. It is not our mod. optifine helps resolve most of that visual bug.
