Black rectangle on top of window (sometimes)

[malyninja]

Hi everyone.
I've recently started with SFML and I've got a problem. I was looking for solving but it hard to describe what exactly I want to find. When I set the window to fullscreen, sometimes there is black rectangle on top of window. It looks like the screen has been moved down, because I can't insert even a cursor in this area.

Printscreens:
what I want:

what it looks like if problem occurs:


This problem occurs randomly, sometimes few times in a row, sometimes it hard to catch the problem.

There is no matter how the code looks like, but every time started like this:

sf::VideoMode desktop = sf::VideoMode::getDesktopMode();
sf::RenderWindow window(desktop, "SFML window", sf::Style::Fullscreen);
window.setMouseCursorVisible(false);
window.setFramerateLimit(60);

I don't know if it is problem connected with the SFML or with my system/screen drivers. I use Linux Mint and I installed library by apt-get install.

And now, when I launched my application, this black rectangle was on bottom of thhe screen. I thought that is because the application doesn't detect my screen resolution. I checked and this is output:

1920x1080
1918x1023

code:

std::cout << desktop.width << "x" << desktop.height << std::endl;
std::cout << window.getSize().x << "x" << window.getSize().y << std::endl

But even when the problem does not occu, output is the same.
