I have written a very simple QT edit app using QTextEdit (attached). It
works with both Qt5 and Qt6, and typing Shift, Control, and Alt keys does
not cause any unexpected behavior. So whatever is happening is coming from
Leo somehow.
BTW, you said that you've been using Leo/Qt6 for some time. But I couldn't
get it to run until I fixed qt_text. How did you manage it? I don't know
what qt_text does, really, but it's imported even though it's not in my
enabled plugins list.
