Hi mr-2458,
Sorry to hear of the unwanted behavior from OneDrive menu you're experiencing. And thanks for your screenshot. Based on that, I can see that your Taskbar seems to be at the top of your screen. This likely means that the UI changes in the update might have been rendered incorrectly. To better help, I'd also like to ask if you happen to be using any third-party customization tool?
That could be one of the issues, but first, let's try to reset your Taskbar position to see if it helps:
- Right-click your Taskbar > Uncheck Lock the taskbar (if it was locked)
- Temporarily turn OFF Automatically hide the taskbar if it was turned on
- Change the position of your Taskbar to the bottom of your screen
- Test the OneDrive menu flyout. If it's visible, change to the top again.
If the menu is still hidden after you change the Taskbar to the bottom or/and back to the top, this could be a scaling issue introduced in the latest update. Consider report it directly to Microsoft via Feedback Hub, by pressing Win + F and describing the issue with the screenshot you shared above.
