When you click the "Add project" button in the project list, first you see the "Nothing here" view (see attached screenshot) for a moment before the new project dialog appears. Also, when you are in the newly created project and you click the space breadcrumb, before you see the list of projects, the "Nothing here" view appears for a second. If you create multiple projects, the issue is 100% reproducible.

The "Nothing here" view is only visible for a short time, but it is pretty annoying that it appears every time you want to create a project or navigate to a space.
