There is a problem with showing keyboard on QT 6.0.0 with Widgets. It is not showing after focusing widget by touch (even the simplest QLineEdit).
It seems that the problem is related with wrong qMouseEvent position.
Event position is checked before showing keyboard. In the attached sample code it is shown, that Y value is lower than 0. For sure this value is not correct, and that is why the keyboard is not showing.
The bug is NOT reproducible by mouse click.
The bug is NOT reproducible on 5.15
