After longer period with 0.94 I have noticed some strange activity with my phone. It seems like my N9 have I mood of its own. Sometimes it works very fluid and scrolling in app drawer and events screen is about 60fps. Then after couple of hours without a reason phone starts to lag a little and fps is dropped maybe somewhere 20-30 fps. Then again after random hours it gets back to super-smooth.

This is kind a strange because there is no pattern when this happens. It happens very randomly. I thought it would be swap issue and downloaded Drop Cache, but no effect there. Is there anyone who have same issues with 0.94?
