An vertex selection error in qtViewer via PySide6 #78
Description
When using the pyside6/pyqt6 backend, I tried to select the vertex at a .stp file, but when I change to the vertex selection mode, I find that cursor can't locate the vertex exactly, all points needs cursor keep an strange offset to highlight.
When change to pyqt5, the vertex selected as expected.
I don't know what cause this. How to solve the problem under pyside6?
This problem can be repeated in examples\core_display_signal_slots.py, via change this line from qt-pyqt5 to pyside6
display, start_display, add_menu, add_function_to_menu = init_display("pyside6")
