Hi, I'm teaching myself how to use affinity designer and I'm still a novice. I don't do very complicated things on it. I have been trying to make a logo for a new business I'm working on and my simple graphic seems to have glitches and I'm not what's going on or what I'm doing wrong or how to fix it. It looks find with it's layers and zoomed out but when I zoom in it gets these little cut-outs. The layers are pretty much all just lines created with the pen tool. When I rasterize the image or try to export it as a png it does the same thing with the cut-outs. Also, when I zoom in more, the location of them change. This does not happen in other images that I have created. If I copy and paste it into a new document, it still has the cut-outs, as if they are part of the lines, but I don't understand why. Thank you for your help. I'm very lost and frustrated.
