Describe the bug
Excessive consumption of RAM by Minecraft when using fancy menu. I also want to mention that Minecraft has only 2 gigabytes of RAM allocated.

To Reproduce
Just launching minecraft.

Expected behavior
That minecraft won't consume so much RAM.

Game Log
There are no logs, this is not a critical error.

You are probably loading pretty large sound files or pretty large animated textures (APNG, GIF, FMA), slideshows, cubic panoramas or FancyMenu's old animation format (deprecated now). FancyMenu will never consume 6-7GB of RAM without using way too large assets.

If you don't load large assets, try to start the game with only FM + dependencies installed. Could be a mod conflict then.
