Description Koichi Yoshida 2019-07-26 12:32:31 UTC 
I found a problem that SDL_UpdateWindowSurface() failed for a window resized by SDL_SetWindowSize().
The window is created as "not full screen" and resizable. 

I have attached a reproducible code for the problem.

Tested environment:
	debian 10.0.0 amd64
	sdl2.0.9+dfsg1-1

How to reproduce the problem:
	gcc sdl2_UpdateWindowSurface_failed.c -lSDL2 && ./a.out
	In case of SDL_UpdateWindowSurface() failed, you can see an error message as follows.
	> SDL_UpdateWindowSurface failed: Window surface is invalid, please call SDL_GetWindowSurface() to get a new surface
