[Python] QMessageBox has clipped children widgets

I have a QMessageBox.question object that I use to confirm that the user wants to close the program. I also have a custom one that I use for showing errors. For whatever reason, since using PyQt6 they are appearing clipped? Where the text, buttons, and I con are all cut off, like this:

response = QtWidgets.QMessageBox.question(None, 'Question', 'Do you want to continue?',
QtWidgets.QMessageBox.StandardButton.Yes | QtWidgets.QMessageBox.StandardButton.No)

print("Response:", response)

sys.exit()

• Python: 3.10.12
• PyQt6: 6.9.0
• PyQt6-Qt6: 6.9.0
• PyQt6_sip: 13.10.0

Is there something I can do to fix this? It makes the program look very unpolished.
