[Interest] how to get 3 pixel focus ring?

[Kevin André]

Just speculating without really knowing anything about this, but...

Have you made sure that there actually is enough space for painting
that focus ring?
Up until now I had never heard of a "focus ring", but after looking at
the screenshots, it seems that it is simply a wide border around a
widget that is only visible when the widget has focus. But if a widget
was not designed to have such a large border around it, there might
simply be no room around the widget to paint your focus ring and then
anything you try to paint might simply be completely or partially lost
by clipping. This could explain why your experiments show a partial
result on Mac but no result at all on Windows; Qt might put some extra
space around widgets on Mac but not on Windows just because both
platforms have their own style that Qt tries to mimic.

What i want is the style you get around a text edit on mac, but i want that style on ALL widgets, and i want it on windows too.
