What's Wrong?

Desktop rendering does not work properly on macOS sequoia 15.7.2 for version Claude 1.2773.0. When sidebar is open, everything within a certain length to the right of the sidebar is truncated and does not display and gets cutoff, including chat name in top left, or a lot of the display when you open a project.
