Floating QML Rectangle shows flickering in free-scale overlay buffer



  • We have one QT quick application which creates a floating QML rectangle.
    It runs on free scale board and selected display buffer overlay buffer(i.e frame buffer 1 ).
    But, this rectangle shows flickering when we drag it.

    Note: We have selected frame buffer 1 using command
    export QT_QPA_EGLFS_FB=/dev/fb1
    There is no flickering issue when we run it on default display buffer( frame
    buffer 0).

    Any idea/ suggestion?

    Regards,
    Arun
