Python segment does not activate/show outside Python folders

What happened?

I was experimenting with the Python segment and it did not work as expected.

To my understanding .Venv is defined when a virtual environment (venv) has been activated and it will have the value of environment variable VIRTUAL_VENV_PROMPT.

When display_mode is set to always I expect the segment to always be shown. But it does not always, even when a venv is activated.

When I activate a venv from outside of any 'Python folders' then the segment is not shown. When I then make a 'recognized Python folder' my current directory (e.g. folder "venv") then the segment gets displayed and stays displayed even when I move out of that 'Python folder' again. The segment is not shown unless triggered by some other rule than {{ if .Venv }}. Once displayed it appears to behave as expected.

Here is my Python segment code (I tried both below templates (one currently commented out) and the default template. All experience the same issue):

{
    "type": "python",
    "style": "plain",
    "foreground": "#393fd4",
    "properties": {
        "display_mode":" always"
    },
    "template": " {{ .Full }} {{ .Venv }} "
    // "template": " {{ if .Error }}{{ .Error }}{{ else }}{{ if .Venv }} {{ .Full }} {{ .Venv }}{{ end }}{{ end }} "
}

The  above is a nerdfont Python symbol.

Example directory structure:

source\python\venv\myvenv

myvenv contains the virtual environment.
I activate it with source\python\venv\myenv\Scripts\Activate.ps1 (the path before source is omitted here).
When source is my current directory when I activate myvenv with above Activate.ps1 script then the Python segment is not shown. When I then change my current directory to venv the segment suddenly is displayed. When I then change current directory to source again the segment is still displayed.
The Python segment should be shown, independent of from within which folder I activate a venv.

[lnlp]

Additional information:

On a different computer (at totally different location) the issue does not occur.
On this computer everything is located on the C: drive and Python version used is 3.7.9.
On above computer where the issue occurs the source folder is located on the D: drive and Python version is 3.13.1.
Possibly one of these differences is related to why the issue is occurring on the first computer and not on the second.

Versions tested:
Oh My Posh 24.11.4
PowerShell 7.4.6
Python 3.7.9
Windows 10 22H2

In your logs above it shows the environment, so I would need the logs when it doesn't. But it's going to be something silly (and probably by design).

[lnlp]

What do you mean exactly?
The logs from when venv is active but OMP prompt does not show the Python segment?

[JanDeDobbeleer]

@lnlp yes, when the issue is visible. Because here I can see it displays what it should.
