I had this same exact problem last week.
You can try what JC suggested, but that actually didn't work for me. Pressing down on the trackball and spraying canned air made a lot of sense to me, but I didn't have a can at home.
Before running out to get a can of compressed air, I tried cleaning the trackball with a Q-Tip and alcohol. That picked up the debris and it's been perfect since.
