hello:
I want a screenshot,
so I use the glReadPixels to read the screen pixels, but nothing to be readed, glGetError() returns the GL_INVALID_OPERATION,
Is TDA4 don't support?
by the way, the same usecase, It's ok on windows.
----------------------------------------------------------------------------------------------------------------
glReadPixels(0, 580, 100, 100, GL_RGB, GL_UNSIGNED_BYTE, _pTexture);
