Docker Desktop reports incorrect VM memory usage

DaRosenberg commented 1 year ago

[X] I have tried with the latest version of Docker Desktop
[X] I have tried disabling enabled experimental features
[X] I have uploaded Diagnostics
Diagnostics ID: 11D636E8-67DA-46AF-938B-942EB1F9D7B7/20221205101857

Expected behavior

VM memory usage reported by the app should at least roughly match the configured memory resource usage.

Actual behavior

VM memory usage is incorrect by as much as 9 GB or 37 %.

It cannot be explained by looking at the oher Docker-related processes on the machine:

Information

macOS Ventura 13.0.1, Intel chip. Docker version 4.14.1.

Steps to reproduce the behavior

N/A

Seeing similar problems on our end as well. "VM CPU Usage" seems to give meaningful numbers, but "VM Memory Usage" doesn't make sense.

When I start Docker Desktop it immediately says "VM Memory Usage" is 16GB, which is the max allocation set in the resources settings.

Hope this helps! Thanks.

Same issue: Docker Desktop on macOS Ventura. Settings are 7GB. Activity Monitor says 7.02GB. But status bar of Docker Desktop says 11.17GB.

What I have observed is that “VM Memory usage” displayed at the bottom is = (VM memory + Container memory), as soon as I stop all containers, it matches the number shown in activity monitor.
