93a520b385 Fixed bug 3605 - Software renderer no longer renders after Android screen orientation change
Sylvain

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.

0e45984fa0 Fixed crash if initialization of EGL failed but was tried again later.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
