QML TextInput slow to give up focus on Windows

[poncho524]

I have a form with a TextInput and a button. if i type into the TextInput and try clicking the button, the button doesn't respond right away. After entering text into the input field, i need to wait at least 1 second before i can click the button.

This only appears to be a problem in windows. I am not doing any validation or any extra processing. this is strictly QML only.

Anyone else able to confirm or deny?

real simple case:
just start clicking on the button as soon as you enter text in the input

import QtQuick 2.15
import QtQuick.Controls 2.12

Item {

    TextInput {
        id: textInput
        width: 100
        height: 30
    }

    Button {
        anchors.top: textInput.bottom
        height: 50
        width: 100
        text: "here"

        onPressed: {
            console.log("click");
        }
    }

}

and its almost exactly 1 second delay

Ends up this is a Windows problem. any keyboard input delays mouse input for 1 second. i have no clue how to turn it off, but there it is.
