This is specific to the kde5 VCL plugin. It works as expected when using e.g. the gtk3 VCL plugin instead. Version: 6.3.0.0.alpha0+ Build ID: cb52b112c0d44d7a6849f773fd1ee4e863ab91da CPU threads: 4; OS: Linux 4.18; UI render: default; VCL: kde5; Locale: en-GB (en_GB.UTF-8); UI-Language: en-US Calc: threaded Steps to reproduce: 1) open LibreOffice Writer 2) "Tools" -> "Customize" 3) in the "Menus" tab, add a menu entry by moving a function to an existing target (e.g. just move the "100%" function to the "File" target) 4) click "OK" button to confirm Result: * The top-level menu entries are no longer labelled correctly (e.g. "~File" is shown instead of "File", "~Edit" instead of "Edit"). * clicking on any of the menu entries has no effect. Expected result: * Menus should continue to work properly. * The new menu entry (e.g. "100%" in the "File" menu) should be there. Note: Everything is as expected again after restarting LibreOffice.
