    Has anybody experienced such bug with UI on 10.8.5 which I've recorded and it can be seen on Youtube

    As You can see, it works very slowly, leaving strange artifacts when I turn fullscreen mode on and off. It happens not only with Safari, but with any other App too. Also I can feel a bit slower response of all Graphic UI but Dock. And speed of system at all is still at normal level.

    I've tried different ways to repair it, but the bug is still there. Maybe someone know what shall I do?

    Here are specs: MBP 2012, 13", 128 SSD, 500 HDD, 8 GB. Mac OS 10.8.5

    P.S. sorry for my English
