Example code showing only blank screen on Debian Sid

SDL fullscreen mode (SDL_WINDOW_FULLSCREEN_DESKTOP) shows only blank black empty screen on Debian Sid. Same code works correctly in windowed mode.

This is either SDL2 bug or Debian Sid X libraries are buggy. Fullscreen mode works correctly in Debian stable (virtualbox machine without latest nvidia drivers).

You need to call SDL_PollEvent or SDL_PumpEvents regularly (typically in a while-loop every frame, in SDL_PollEvent's case) for the window to respond and display as expected.
