Hi Axel, Our device is imx6 with protocol B multi touch screen and mtdev enabled in yocto configuration. Can you please let me know if the patch mentioned in https://bugreports.qt.io/browse/QTBUG-86013 is relevant and can be applied to Qt 5.15 since it is incorporated only in Qt6?
Have you ever experienced touch not responding on an imx6 device with above configuration at times when a button is clicked in Qt Quick application ? Appreciate your feedback in this regard.
