Weird problem with a Winforms application and Windows 10 scaling

Hi guys,
I have a really simple Winforms application written in C# with VS Professional 2022 (64-bit) version 17.2.4 and .NET Core 6.0.

It's a form that contains a tab control that contains a table layout panel that contains a listbox.
Every child control is set to anchor to Top, Bottom, Left, Right.
The expected behaviour is, when I resize the form, every child control resizes accordingly.
But this is true only if I scale Windows 10 to 100%. If I switch to 125% the children controls go crazy.

This is the form at 100% scaling

And this is the same form at 125% scaling
