    Default show() vs showFullScreen()

    I am making an application to view an IP Camera on a Video Widget.
    When I make my MainWindow show(), the camera works perfectly well without any lag but of course I get the top bar.
    When I use ShowFullScreen(), my camera generates a significant lag.
    I find this rather strange. What can be the reason?

    Default Re: show() vs showFullScreen()

    Is the size of the video display area the same or is it larger when you use show full screen?

    If the latter, then maybe you are hitting a limitation of how many pixels can be processed in a given time frame.

    Cheers,
