What does yellow tinting represent when using “color misaligned images” on iPhone/iOS

Qestion


so--i switched on "color misaligned images" to improve drawing performance in our app (Spot). The documentation states:




Puts a magenta overlay over images
whose source pixels aren't aligned to
destination pixels




I don't know what the yellow means however. (There is a "Color Offscreen-Rendered" option that uses yellow... does "Color Misaligned Images" also turn on this option?)



Anybody know?



TIA



Answer

If I remember correctly, the yellow overlayed sections represent views/images that must be blended with underlying views to render the final view - ie. they have alpha channels.
