**System Information** Operating system: Windows-10-10.0.19042-SP0 64 Bits Graphics card: NVIDIA GeForce RTX 2080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 466.27 (2 times) **Blender Version** Broken: version: 3.0.0, branch: master, commit date: 2021-12-02 18:35, hash: `rBf1cca3055776` Worked: (newest version of Blender that worked as expected) **Short description of error** Header Bar in the Layout View collapses suddenly (to avoid confusion it is the top bar with the tabs for File, Edit, Render, etc ...). It collapses to about 1/3th of the original and required height making the bar unusable till expanded to original height again. This can be done by hovering the mouse over the top border of the collapsed bar and dragging it upwards. **Exact steps for others to reproduce the error** The reproduction again seems difficult. This error appeared in the beta version of 3.0 and still is there in the official release 3.0. I had this error twice after saving the file with the "Save As" menu{F12737190}. [Based on the default startup or an attached .blend file (as simple as possible)]
