--- Comment #26 from Henri Verbeet hverbeet@gmail.com --- (In reply to Bob Duke from comment #25)
After updating wine to wine-5.1-1.fc31.x86_64 in Fedora 31, the gdi workaround no longer works. The main menu entries are missing again.
The issue is likely that you're using the "DirectDrawRenderer" registry setting (as mentioned in comments 23 and 24). That setting was deprecated in Wine 4.0, in favour of the more generic "renderer" setting. In Wine 5.1, the "DirectDrawRenderer" setting was removed.
I.e., try renaming "DirectDrawRenderer" to "renderer".
