Ok, fine
I uninstalled any non-official GNOME extension and in cold start I'm
getting after 1.2h of uptime 200MB more than the normal, I am not 100%
sure but I think this still persist
Cold start:

Title:
Unreasonable NVIDIA GPU VRAM usage on gnome-shell
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
GPU: NVIDIA GTX 1060 3GB
Ubuntu: 19.04, Kernel Linux luky-pc 5.0.0-8-generic #9-Ubuntu SMP Tue Mar 12
21:58:11 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
NVIDIA driver version: 418.56
Display settings: BenQ XL2411Z, 144Hz monitor, 1920x1080p
I have noticed this strange behavior only on gnome-shell where the overall
gnome-shell desktop VRAM usage was taking up to 1GB of GPU VRAM which does not
happen on other desktops, or on Windows, happens after some hours of normal
desktop usage
Even the system RAM increases a lot during normal usage, but remains
acceptable
This behaviour can be observed by using "nvidia-smi" a tool from the
NVIDIA proprietary driver
gnome-shell VRAM usage on a cold start: 139MB, + 9 MB
X.org VRAM usage on cold start: 48MB + 18MB
Total: 214MB
gnome-shell VRAM usage after some hours of normal usage: 445MB + 83 MB
X.org VRAM usage after some hours of normal usage: 244MB + 18MB
Total: 800MB
On windows or other desktops the GPU VRAM usage remains the same
