Weird grey objects appearing on pages
I updated my OS today -- and I'm having major problems with InDesign. For one, it's running slowly. More distressing, however, are the strange dark grey angular objects that are appearing on pages. They appear and then disappear and then reappear. See attached screenshots. Those grey objects are NOT part of my page design. I have no idea where they are coming from. This is a file created two months ago, and this is the first time I've encountered this problem. I'm using InDesign CC.
I'm having the exact same issue. Just purchased a brand new MacBook Pro and all of my documents, new and older are experiencing the grey angular objects and my text is appearing distorted.
