Description Sylvain 2018-12-15 15:14:59 UTC 
When switching between renderers.
software -> opengl -> opengles2 -> software

It fails re-creating the software renderer.

"software -> opengl    -> software" would work
"software -> opengles2 -> software" would work

It appears "opengl -> opengles2" frees "window->surface" without marking it as invalid.
So, when doing SDL_GetWindowSurface, SW_Renderer re-creation fails.

test case

test case to switch renderers (actually same as bug #4425)
Comment 2 Sylvain 2018-12-15 15:23:33 UTC 
"opengl -> opengles2" calls SDL_RecreateWindow() which frees "window->surface" without marking it as invalid.

When SW renderer is re-created it fails getting its surface.
