I keep having an issue with white boxes obscuring portions of my files when I am zooming in and out or saving the image. It happens when I try to flatten the image, save as a PDF, or save as a JPG. Prior to updating to version 22, I had found a workaround to the issue by using the Legacy Compositing checkbox. However in this version, that option is no longer available and I cannot find any way to stop the boxes now. I am running on a Macmini using macOS Catalina. Someone please help!
