I noticed some issues with the new iMac 2020 (27 - 3,8 GHz 8-Core Intel Core i7 - AMD Radeon Pro 5500 XT 8 GB) and the InDesign preview. The colors look different when using the GPU preview. It's exactly the same problem in Illustrator. The CPU preview looks just perfect in both programs. I tested it with an older iMac model (2018 I think) and the Radeon Pro 570 4 GB. Everything looks fine there (both previews). Any ideas? Maybe I changed some settings I can't recall?
