I've been trying to have text rendering in my OpenGL scene using SDL2. The tutorial I came across is this one Rendering text

I followed the same code, and I get text rendering fine. However the issue I'm having is that there is obviously a "conflict" between the OpenGL rendering and the SDL_Renderer used in the code. When I run my scene the text displays but everything else keeps flickering. The following gif shows the issue:

Any idea on how to overcome this while still just using SDL2 and OpenGL, not another library or anything.

Thanks

There is a problem using SDL_Renderer with OpenGL. You can save the text to a Surface, and then use this example: http://www.sdltutorials.com/sdl-tip-sdl-surface-to-opengl-texture
