Hi,
My application updates the whole screen frequently, but there are a few situations that updates only a very small part of the screen.
I already tried to use glScissor and/or glViewport to make eglSwapBuffers update only a small part, but the rest of the screen is black. Is there a way to let opengl update only a small part of the screen? Or copy the contents of the back buffer into the front buffer and then update the whole screen?
thanks
