SDL_WINDOW_MAXIMIZED bug?

I created a window with flag SDL_WINDOW_MAXIMIZED, like:
Code:
SDL_Window *win = SDL_CreateWindow("Test", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 928, 928, SDL_WINDOW_MAXIMIZED | SDL_WINDOW_RESIZABLE);

When I call SDL_RenderCopy(renderer, texture, NULL, NULL), I see strange result:
1. It copy only a part of a texture (looks like 928 x 928 in size). My texture is bigger in size than the window.
2. Copied image is not resized to window size. The size of image is only a part of window area with black space at top and at right of an image.
3. Copied image started by y-coordinate not from 0, but from 15. I see black space above image 14 pixels in height. Looks like an image aligned to bottom-left corner of a window, but not to top-left.

This tested on Linux (Ubuntu) with Mate desktop, my screen size is 1280 x 1024.
Is it a bug or I am doing something wrong?

SDL_WINDOW_MAXIMIZED under Linux/X11 seems to be somewhere between
"buggy" and "flat-out not implemented". See
https://bugzilla.libsdl.org/show_bug.cgi?id=2793 for example. I've been
meaning to take a closer look at it, but I want bug 2793 resolved one
way or another before I start working on any more patches.
