In the file AndroidEGL.cpp, when adding EGL_PROTECTED_CONTENT_EXT to eglCreateContext,eglCreatePbufferSurface,eglCreateWindowSurface，then pack my app，it’s fps stays less then 10, without this flag, it’s fps keeps 40-50. I create a simple opengles app using android studio，same adding EGL_PROTECTED_CONTENT_EXT flag， it’s fps keeps 50-60. How can i fix this problem in UE?
