[bionic] gnome shell overuses memory causing overheating
Status in gnome-shell package in Ubuntu:

Bug description:
My laptop with an i7 10750H CPU and NVIDIA 2070 MaxQ GPU undergoes
overheating often. I checked the CPU usage and it is gnome-shell over
using the memory. it seems to use about 1.5GB of RAM, which is very
suspicious.
