This has been happening to me since 1.5 something if not earlier. I quit playing because of it. Now I've done a fresh OS install of Linux on different hardware, installed Minecraft, and it's still doing it.
Randomly, after anywhere from 2 minutes to 2 hours, Minecraft will somehow cause the X server to use any CPU cycles not used by anything else, pegging the task manager to 100%. Minecraft slows to a crawl at one frame every 1-5 seconds. If I can manage to exit the game, it goes back to normal. The rest of my system seems unaffected.
I've never had this problem with any other applications, ever. Although it's X server that's displaying the high CPU, it's definitely Minecraft that's actually showing the effects and I'm pretty sure it's causing it as well.
Dual core, 8 GB of ram, CPU and GPU are not overloaded or overheating. Definitely not a hardware issue. and the hard drive is not thrashing, power supply is rock solid and at less than half capacity. I've tried updating LWJGL manually, rebuilding drivers, setting CPU priority, nothing helps. Using Linux Mint 16 (Ubuntu) with its latest kernel and drivers.
