When using Android13 and GBoard (the Google soft keyboard pre-installed on many devices), if you tap a text field at the end of the current text, giving keyboard focus to the control, then start typing to add more text at the end, the control repeats the last word that was initially in the text field. See video.

The problem occurs with Android13 and Gboard, and with all the Qt 6 versions I tested.

It doesn't occur with Android 13 using other soft keyboards.

It doesn't occur with Android 8 and GBoard.

Sample code used for testing:

import QtQuick
import QtQuick.Controls

Window {
    visible: true
    title: qsTr("Hello World")

    TextField {
        text: "Initial contents"
        x: 50
        y: 100
        width: 300
{{    }}}

    TextField {
        text: "Another field"
        x: 50
        y: 200
        width: 300
{{    }}}
}
