I am running LibreOffice 6.4.4.2 (x64) (Build ID: 3d775be2011f3886db32dfd395a6a6d1ca2630ff) on Windows 10 Version 2004 (OS build (19041.329). After using any of the tools, after a few minutes, the drop-down menus are blank. They start out with the normal sub-menu items at first. This problem is very repeatable except for the number of minutes or operations before the drop-down menu goes blank.
Is there some way I can log information so I can determine what is causing the problem I am soon going to be forced to abandon LibreOffice.
