"Jumping" Effect with Navigation Menu

Problem

When loading a page, the content briefly shifts downward and then returns to its position, resulting in a "jumping" effect.

Why is this happening?

This issue arises because Atlassian’s platform allocates space to load the SubSpace Navigation app (and any other apps installed on a user’s Confluence instance), then releases it once the load is complete. This process causes the "jumping" effect.

Solution

This behavior is a consequence of Atlassian's platform architecture, and currently, there is no solution available to address this issue.
