Fixed bug 4041 - Android, SDL_Renderer OpenGLES 1 is loading GLESv2 library
Sylvain On Android, if you set no attribute using SDL_GL_SetAttribute(), and try to create a SDL Render OpenGLES 1: - it loads first by default GLESv2 libraries - creates the rendere OpenGLES 1 - recreates the Window to have a context 1.1 ( https://hg.libsdl.org/SDL/file/4db4cfd59470/src/render/opengles/SDL_render_gles.c#l298 ) But it doesn't unload libraries, then reload GLESv1 lib. So the SDL_Renderer OpenGLES 1 is working with GLES 2 libs, which seems inconsistent. If you, at first, set SDL_GL_SetAttribute(SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_PROFILE_ES); SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 1); SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 1); It will correctly load GLES v1 libraries. Here's a small patch to reload egl libs when SDL_RecreateWindow() is called. It fixes the issue, also the case from bug 4042 ( SDL_RecreateWindow() is used by SDL_Renderer gl, gles1, gles2. )
