I found a way to eliminate the problem (I think). I went into CompizConfig Setting Manager --> Effects and turned off all the effects like wobbling, water effect, motion blur and fading window). I don't not if the problem will reoccur but so far the border problems have stopped appearing and every thing is good again. Monitoring the situation.
