Canvasjs and HTML5 Charts fixes

Need few fixes on my charts which use both canvasjs library and HTML5 canvas 2D context. For example, in the video link below you will see 2 different charts the first one on black background has a lag when mouse wheel is used and the second chart on white background is very smooth. Need someone with good knowledge of HTML5 canvas and canvasjs for fix performance issues like this.
