Created attachment 129987 [details]
Screen shot showing the toolbar covered by the tab bar.
By default, Libreoffice used one window per document but now it opens documents in tabs (even preferences window opens in a tab). In macOS, the tab bar is covering the toolbar which makes the toolbar unusable. As a workaround, I have to drag the tab until it detaches from the tab bar and shows as a separate window.
The attachment shows a new writer doc opened as a tab in a window where there was originally a calc doc.
Solved using the workaround suggested for the bug reported as 103496.
