Issue
I am writing a program in Pyside6 and use my own Titlebar.
When running with pyside6, I get this problem.
I need to remove this space
Using PyQt5 everything is fine
What differences in the work of these frameworks can cause this problem and what should be used to fix it. the code on both frameworks is the same, but the result is different, I can't understand why this is happening

Solution
The reason is that the named arguments to QVBoxLayout are not supported
layout = QVBoxLayout(self, spacing=0)
The property needs to be set by calling the setter.
layout = QVBoxLayout(self)
layout.setSpacing(0)
