On Ubuntu 23.04 (but not on Ubuntu 22.10) LibreOffice Impress does not properly enter slide-show mode, which should be entirely full screen.
Instead, Impress shows a window title bar that reads "Presenting: " and the name of the file.
How do I configure Ubuntu so that Impress will present properly in full-screen without this title bar?
I have tried both LibreOffice 7.5.2.2 and LibreOffice 7.4.6.2 on Ubuntu 23.04, and both versions have the same problem, but 7.4.6.2 entered full-screen presentation mode fine on 22.10. This leads me to think that the issue is Ubuntu 23.04, not Impress -- or at least how Impress is operating with 23.04.
Other applications correctly enter full-screen mode on my 23.04 system: GIMP, darktable, Firefox, etc. All the others work fine in true full-screen mode.
