Also, I found out it has to do with the "Enable decoding of Indexed textures" setting. If enabled, AF effect is broken on r2324+. If it's not enabled, AF works as it always did. I turned it off also as a noticed bad texture bugs with this enabled on 3rd Birthday. Not sure if those have always been there or something just messed up this option's functionality period. Blocky shapes appear on Aya if this is enabled.
