Our platform is using the PowerVR® BXS 4-64 MC1 core GPU, and then we try to turn on hardware anti-aliasing during EGL inti. The following is my code diff,
However, once EGL_SAMPLE_BUFFERS, 1, EGL_SAMPLES, 4 are added, EGL will fail to initialize where eglsurface is created (eglCreatePixmapSurface) and return 0.
I also tried to print out all supported config attributes. config[3] supports EGL_SAMPLE_BUFFERS, 1, EGL_SAMPLES, 4,.
Do you have any suggestions for this?
