I downloaded Affinity Designer for MAC and now have purchased Photo and Designer for my Windows machine. Same complaint all way round. The black background makes it very difficult to work. It actually hurts my eyes. PLEASE create a patch that allows for a white background. I still use my Serif Draw Plus 8 because it is that difficult for me to see and I am trying to transition to all MAC office but this is a hindrance. Otherwise nice product and I look forward to using it more.
