Qt for Python (PySide/Shiboken)

Is using from __feature__ import true_property incompatible with loading Ui types via PySide6.QtUiTools.loadUiType? When combining both, I always get a traceback ending with self.ui.setupUi(self) File "<stdin>", line 24, in setupUi TypeError: 'str' object is not callable It seems that the type object is interpreted as having true_property enabled, while the generator does not create appropriate code for that.
