Hi:
Django version: 3.2.4
Python version: 3.8
I cannot reproduce this bug in a simple example, so I can only show you
screenshots from my Pycharm Debug Tool, I am sorry.
I have one queryset with 3 objects which contains annotations, CharField
and ManyToManyField attributes. Then I filter by a query using Q like
this:
{{{
(OR: ('created_date_dt_custom__icontains', 'a'), ('id__icontains', 'a'),
('title__unaccent__icontains', 'a'), ('created_date_dt_custom__icontains',
'a'), ('id__icontains', 'a'), ('title__unaccent__icontains', 'a'),
('promoters__in', <QuerySet [<User: admin>, <User: u********>]>))
}}}
And gets a queryset with 4 objects as a result, one of the objects is
duplicated. If I delete the last filter ('promoters__in', <QuerySet
[<User: admin>, <User: u********>]>) it works fine, so the problem is on
this filter or maybe the concatenation of filters with this kind.
I have no problem on Django version ~= 2.
Here are the screenshots of my debug tool showing the problem:

- Screenshot of debug tool with variable values (Project object (19)
duplicated): https://i.ibb.co/b34FwSM/ss2.png
Thank you in advance, hope it is fixed soon,
Ismael.
