Fullscreen widgets under GNU/Linux

[gagiD]

Hi,

I wrote this function for fullscreen:

void Player::setFullScreen(bool fullScreen) {
    Qt::WindowFlags flags = windowFlags();

    if (fullScreen) {
        flags |= Qt::Window;
        flags &= ~Qt::SubWindow;
        setWindowFlags(flags);

        showFullScreen();
    } else {
        flags &= ~(Qt::Window | Qt::SubWindow);
        setWindowFlags(flags);

        showNormal();
    }
}

And after some time it crash:

What should I change?

Hi,

Can you give more information about your crash ? e.g. a stack trace ?

Just to be clear, it's not app crash, I did not describe it good.
Sometimes fullscreen mode look messy(look at image), let say it's happening every 10th time.
But, I can exit from that messy fullscreen and video plays in normal mode.

I tried:

resize(QApplication::desktop()->width(), QApplication::desktop()->height());

But no effect.

I have Gamma Ray, I guess it can help.
Which informations are relevant?
