This is not related to kernel. I've tried version 4.3 (http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/) in Ubuntu 14.04 and the problem remains. It really looks like it has something to do with other programs based on Java. As soon as I close PhpStorm, the problem disappears in other programs.
