If you set the egl config like the following: conflist[i++] = EGL_RED_SIZE; conflist[i++] = 8; conflist[i++] = EGL_GREEN_SIZE; conflist[i++] = 8; conflist[i++] = EGL_BLUE_SIZE; conflist[i++] = 8; conflist[i++] = EGL_ALPHA_SIZE; conflist[i++] = 0; And you try to transform with a color (like 0x11223344) then the alpha part of it is skipped. This is in contrary to the Khronos reference implementation. (I have to admit for images it seems to work nearly correctly - i will make another ticket for an other issue.)
