@vvoland @dvdksn can you take a look?
I'm not able to reproduce. docker images --filter "dangling=false"
produces the correct results for me on both Docker Engine 20.10.22 and 23.0.2
@vvoland any better luck for you?

I'm only able to reproduce this for certain images, for example in the following there are two images which have a repository, but no tag. These are listed in both filter options.
In the output below, the following images are listed for both filter options:

Since they show in dangling=true
, I assume they're dangling, but maybe there's more to the story?
Here's a docker inspect
of one of them:

Description
Documentation for

Unfortunatel this lists the same results as not specifying a filter at all.
Reproduce
docker images --filter "dangling=false"
Expected behavior
Only images which are not dangling should be shown.
