Fullscreen-Errors with sf::RenderTexture/sf::RenderWindow ?

[NaCl]

Hi!
I wonder why, but if I create a sf::RenderWindow(sf::VideoMode::getFullscreenModes()[0], "blabla", sf::Style::Fullscreen) together with a sf::Rendertexture, I get a 800 by 600 resolution, not a 1600 by 900 resolution. (sf::VideoMode::getFullScreenModules()[0] width: 1600 height: 900)
No scaling! I have no idea why it is 800x600 and not 1600x900... I mean, I have the Hardware to use such a sf::VideoMode! ._.

How do you know it's the small resolution?
Can you provide a complete and minimal example?

Well lets say I create a sf::RectangleShape on the position 400|300.
Then its right in the middle of the screen. On (800|300) it isnt visible anymore. So yeah...
Ive had a long Debug-Session.

I solved it.
There was just a wrong operator in my code, which was hard to localize. Thanks anyways!
