This still happens with the current trunk version. (software renderer of testdrawchessboard.c)
When there is a rotation, the window size changed and the internal surface is marked as "surface_valid == SDL_FALSE".
And all further call fails.
SDL_video.c :
2478 void
2479 SDL_OnWindowResized(SDL_Window * window)
2480 {
2481 window->surface_valid = SDL_FALSE;
2482 SDL_SendWindowEvent(window, SDL_WINDOWEVENT_SIZE_CHANGED, window->w, window->h);
2483 }
some error set to :
2233 return SDL_SetError("Window surface is invalid, please call SDL_GetWindowSurface() to get a new surface");
So, this seems to be the behavior of the API ...
In the loop() function of testdrawchessboard.c, we can recreate the surface/renderer :
65 if (e.type == SDL_WINDOWEVENT)
66 {
67 if (e.window.event == SDL_WINDOWEVENT_SIZE_CHANGED)
68 {
69 surface = SDL_GetWindowSurface(window);
70 renderer = SDL_CreateSoftwareRenderer(surface);
71 }
72 /* Clear the rendering surface with the specified color */
73 SDL_SetRenderDrawColor(renderer, 0xFF, 0xFF, 0xFF, 0xFF);
74 SDL_RenderClear(renderer);
75 }
And it displays correctly.
