Slucham i rysuje

I have the same problem. I guess it has to do with the projection mode - I use analogous solution in ProCreate. And it’s handy - you can than use the secend screen to showcase the progress of your work. However it does not work well of I want to use the second screen as my working screen. In Procreate there is an option to switch the project canvas on and off. I am also looking for a tip on how to change it in Affinity Designer.
