Smoothie charts render differently if I open another tab or scroll up/down #118

I've been experiencing this bug where the chart renders a lot more points when I open a new tab, or when I scroll up/down very quickly. Any thoughts of what could be ?

I upload some screenshots so you can see more clearly :

This is probably a problem with power optimisation from the browser:

Fast scrolling does not allow enough cpu cycle to fullfill the settimeout/requestAnimationFrame timers

Thank you for your help ! Im glad to say I fixed the issue by limiting the FPS ! Now my charts are rendered correctly !
