Is that on Windows? I use Linux and Mac and haven't had memory leaks. In fact, Chrome is more a problem for me on the Mac since my wife likes to keep Chrome windows open on her profile indefinitely, and Chrome keeps downloading updates on the background and takes a large chunk of my hard drive keeping every version that ever existed in the .App file.

Windows so maybe that is related.

Do note that I regularly have multiple browser windows open (and these are usually on private mode) with 50+ tabs so my usage pattern is not very standard.
