Gnome-Shell – High RAM Usage in Ubuntu 17.10

17.10gnomegnome-shellmemory usageram

I am using Ubuntu 17.10 with the default Ubuntu desktop (no extensions added) and my computer has 4 GB of RAM. I noticed that every time I use Gnome Shell, either by pressing the Super key, Super+A, Super+Tab or by clicking an element on the top bar, the RAM usage of the gnome-shell process increases by a couple of MB. This doesn't seem much of a problem, but after some hours of work gnome-shell usage climbs higher than 1.5 GB, with the total RAM usage being close on 4 GB. Then swap is starts getting filled up, making my computer extremely slow.

Does anyone else notice the same behavior? Why does gnome-shell memory keep adding up? Is there a way to clear gnome-shell memory usage other than logging out?
