I am experiencing an issue where Minecraft would increase the memory usage rapidly, even if the character is motionless or not (moving and/or looking around).

It would do a loop where it would start at 852MB (20%) of memory, it would increase up to 2095MB (51%), then drop back down to 852MB.

This cycle causes my laptop to overheat severely as my RAM is being cycled every second of Minecraft being open. This causes a thermal hibernation. Whilst my computer is trying to hibernate, it is still overheating which causes the thermal hibernation twice every second in Event Viewer.
