Do you have "Increase Contrast" enabled in your MacOS system settings? This was a known issue in build 7102, but was corrected in the next build (7212) and I haven't heard of it happening since. I did just test with builds 7102, 7212, and 7285 on MacOS Ventura and could only reproduce the issue on build 7102. Are you sure you are running build 7285? What version of MacOS are you on?
