We find most gnome-shell bugs are actually bugs in extensions, and you have a lot of those:

I've left my computer running overnight, with all applications closed, just to come back next morning and find my desktop session frozen, and having to kill on of the previously mentioned processes to get back my machine. I've found other bugs, like bug 1856838 but that one focuses on opening the overview, which after opening and closing dozens of times, my memory doesn't increase. Also, bug 1882781 which is marked as a duplicate of the previous bug.
