Admin Menu points moving arround

Hey,

since a couple of days i noticed an Error/Bug on different WordPress sites I have. It happens on different templates and with different plugins. When i Login into the admin area the Menus starts to moving it happens randomly and only in Chrome. I tried Firefox and IE no issues. Anyone got the same issues or have an idea how we can fix this?
