This is a known issue only on macOS 10.14 Mojave with ARCHICAD 22 when opening a 3D view/tab. Our developers are working on a fix to be released in a future update, likely in Fall of 2019 if all goes to plan. We know it is annoying and are doing our best to issue a fix soon. Sorry for the inconvenience.
