I want to use a framebuffer to create an image using a shader program. This works well, except that the Y is inverted. It seems that the bottom left corner becomes the top left corner. Why does this happen? Is this normal? Does this happen on all android devices?
Inside my shader program gl_FragCoord will have inverted Y, depending on if i draw to the framebuffer or to the screen directly.
from Drawing to a FrameBuffer causes Y to be inverted
