I believe this is very similar to, or perhaps the same as the incomplete bug
MC-19539.This code may fix the issue:
This also seems related
MC-3771.I can also confirm that this problem seems to affect MineCraft only. RuneScape for example does not have this issue despite being similarly driven by Java & Open GL.
This a thread dump generated by JStack, not sure if it will help. I've noticed that the CPU also spikes incredibly high for the game when this bug occurs. Unfortunately, my VisualVM client is refusing to function properly so I cannot provide timings at the current time.
EDIT: I don't know if this is related, but VisualVM will simply not allow me to profile my MineCraft client.
This has been resolved, thanks.
I can confirm this occurs for Minecraft 1.7 - 1.12 as well.
