I deleted LibreOffice 6.4.something and installed to 7.3.2. All the pulldown menus have black background and the text for many of the options are black. From Googling, it is possible that this can be solved disabling OpenGL. However, it’s impossible to do this when nothing is visible. Another solution was to remove the user profile folder C:\Users%USERNAME%\AppData\Roaming\LibreOffice\4\user. For me, this did not solve the problem.
Aside from reverting back to 6.4.something, what else can I do?
