Comment 42 for bug 1672297

So does that mean this is a wontfix for 17.10, the current version?

I had to double my RAM to 16GB just to get more than a day out of gnome-shell at work, otherwise as the day goes on, each notification I receive hangs the system for a few seconds and locking and unlocking the screen can take up to a minute by the end of the day. If I happened to be at the bottom of a keystroke at the time it hangs, it acts like the key was held down for the duration - a nightmare in Vim. As others have said, actions like pressing the super key or switching windows seem to consume a few MB each time that it never seems to give back.
