Unreal Editor UI Rendering Issue: Overlapping Menus and Viewport Toolbar Elements

Summary

The Unreal Editor UI appears to render incorrectly, with overlapping menu bars, duplicated Unreal Engine logos, and misaligned toolbar elements. The viewport and toolbar layout also appear inconsistent, with some controls partially clipped or displaced.

The issue persists across different editor layouts, as shown in the attached screenshots. The viewport itself remains visible, but the surrounding UI elements are incorrectly positioned, making the editor difficult to use.

Expected Result: The editor UI should render correctly, with menu bars, toolbars, and viewport elements aligned and displayed without overlapping.

Actual Result: UI elements appear duplicated, overlapped, or misaligned, resulting in an abnormal editor layout.
