Mod for Minecraft 1.8.9 that fixes some memory issues

MemoryFix is a mod for Forge 1.8.9 that aims to fix known memory issues.

Which issues does it fix?

• Optifine cape leak: This is the main memory leak, anyone who has played minigames for a few hours would have experienced it. More information: sp614x/optifine#526.
• Oversized resource pack icons: Some users download hundreds of resource packs and some resource pack makers (looking at you Apexay) put huge icons in their resource packs. This adds up and can use hundreds of megabytes of memory for some users.
• System.gc() on world change: Causes world changes to take a few seconds. The same effect can also be achieved by adding the JVM argument -XX:+DisableExplicitGC.

memoryfix's Issues

Changing packs

When I change pack it puts the memory usage up to around 80%-90% therefore causing lag spikes repeatedly until the game is restarted.

Map textures leak

For example bedwars, murder mystery and prototype lobbies on hypixel. Maybe we should call the clear maps method on change world, for remote worlds.

Doesnt work.

Why doesn't it work!!! i tried on 1.7

Memory bug

Basically when I was playing after like 5 minutes it was starting to lag but when I removed to mod everything was fine.

Packets Being Sent To The Server. CAUSING THIS MOD TO GET YOU BANNED ON HYPIXEL!

So I was using this mod in one of my streams, as it enabled me to do so on the Hypixel server. However, I woke up the next day and was banned by watchdog. So I decided to do a little investigation on this, and I found that packets are being sent to the server pretty consistently.
Below are two packets that get sent to the server. The ARM_ANIMATION packet is the one being sent the most. The second one happens every time you login to the server. The first gets sent consistently as you are playing, more specifically, almost every time you hit, place, or break a block.
31.01 15:48:34 [Server] INFO Received ARM_ANIMATION[class=PacketPlayInArmAnimation, id=29] from Deliberating.
31.01 15:47:37 [Server] INFO Received ENCRYPTION_BEGIN[class=PacketLoginInEncryptionBegin, id=1] from UNKNOWN[/This is an IP, I don't wanna show it ;)].

I'm not really too experienced with making mods and plugins, but I'm pretty experienced with configuring and troubleshooting. I believe this issue is rather crucial to fix as this is causing players to get banned from hypixel, including myself. Which the appeals team denied, as always.

OpenGL Error: 1283 Stack Overflow

This has nothing to do with the mod, but I was just wondering if you could shed some light on this. Basically if you use OptiFine 1.8.9 HD U H8+ and try to press f3, Minecraft will completely render useless, and start spamming "opengl error:1283(stack overflow) in chat. This takes a good 5 minutes to shut down the Minecraft process through task manager and I was wondering why?

Is this something you could fix like you've done previously?
