Comment 9 for bug 1772365

I think what reported by Lorens may be totally unrelated to the use of Chrome. The use of VirtualBox, latest version 5.2.18, with a Ubuntu 18.04 64bit guest with 3D acceleration **enabled** and maximum VRAM configured (128MB) is completely unusable because of extremely high memory usage of gnome-shell, independently of the application launched: you can launch nothing or launch firefox, for example, and the session will become unusable pretty soon. It may be worth some more investigation of VirtualBox+3D acceleration use case. My host is actually Windows 10 64bit.
