I didn't use that app ever but I guess w/ or w/o a gif, it won't use much CPU when it's idle. When scrolling a page-like thing that's already rendered, also then it probably doesn't do much computations. What, at all times, will be overtly consumed is going to be memory space. That may cause battery drainage and general slowness in the OS due to swapping, and even quicker wear-out of storage hardware. AFAIK Chrome takes hundreds of MBs of memory just right after startup, with nothing open.
