Only happens when I try to download files, not sure if there is a threshold for how big the files are or if it needs to be a specific type of file - this just happened whenever I was trying to download a 1gb zip file on the browser. Photo and video attached displaying the problem.

The memory should not balloon to 17GB usage because I am downloading a 1gb zip file.
