Multi coloured noise problem (fuji raf)

[Alice Jones]

I've attached two screenshots of the terrible noise problems I'm having with AP. I love this application but can't work out why my backgrounds are rendered this way. 

 

Will it help if I convert the fuji raw files into a different format first?

 

I've attached a further file today showing the harsher colours in the noise and general colour rendering differences between Lightroom and Affinity. 

 

Thanks, Alice

Affinity Photo does not automatically apply any noise reduction to images when opened in the Develop Persona. This video should help: https://vimeo.com/135040640
