Open LibreOffice Impress, enable Tabbed UI (View -> User Interface -> Tabbed), add a formula and try changing the font size of that formula (i.e. navigate to the tab "Home" and change the font size). The Tab UI is then greyed out instead of the font size being changed.
Benedikt, how did you add your formula? If you used Insert->OLE Object->Formula then you can't change font size from Impress UI. You should enter to Edit formula mode (double click) and then select menu Format->Font size and set up font size there. Or you can use extension https://extensions.libreoffice.org/extensions/formatting-of-all-math-formulas
Roman: Yes, it is an OLE element. Since the Tabbed UI replaces the menu bar with tabs, selecting the menu "Format" is no longer possible. Probably when in OLE mode there should be an OLE tab containing e.g. the "Format" menu, but there is not.

Created attachment 153601 [details] Impress with Tabbed UI, OLE mode Impress with Tabbed UI, OLE mode, menu bar not visible V Stuart: Note that it is possible to manually reactivate the menu bar when in Tabbed, maybe you have done that previously? For me the default is that the bar is hidden and the bar also does not reappear when in OLE mode, as can be seen in the screenshot. Also, while in OLE mode, when I click on the Tab "View" on "Menubar", nothing happens. System: Manjaro KDE stable (Arch Linux, latest version)
I installed LibreOffice btw. through Octopy, the Arch package manager GUI. Therefore, my issue is very easy to reproduce without downloading anything manually: * Install Manjaro KDE stable * Launch Octopy - File->Check updates - File->System upgrade - enter "LibreOffice" - right-click -> install - click "commit" button * Launch LibreOffice - View->User Interface->Tabbed - Insert->Formula (OLE menu bar not shown) - View->Menubar (nothing happens) - Exit OLE mode - View->Menubar (Menu bar appears) - Double-click formula (OLE menu bar is shown)
No, clean user profile on startup, View -> User Interface selected 'Tabbed'. Selecting to edit inserted OLE Formula opens the sm Formula editor with its Main Menu showing. But is the issue that you can't change the size of the formula? Or that the Main Menu is hidden in this MUFFIN mode (and needs to be unhidden)? BTW you should be wrapping the formula in a 'size ## { }' rather than tweaking the sm Format size defaults. => WFM in either case.
V Stuart: My initial issue is that when one is in Tabbed mode and does not know where to change the font size, there is no way to find it out by oneself. This turns out to be the result of the combination of the following two issues: * I don't get the OLE menu bar when the menu bar is disabled, what is the default in Tabbed. Obviously also in default Tabbed, there should be a way to access it. Probably it would be reasonable to put these into an own Tab, but a fix would also be to just show it always as it is in @V Stuart s screenshot. * If in OLE edit mode, the tab buttons are all enabled, but have no effect. When one changes Home->Font size, after a few seconds all buttons are disabled. Probably they are meant to be disabled from the beginning in OLE edit mode, but they are not, leading to the impression that they could have an effect.
I've been making several tests. The issue is that the impress bar is not hidden when you are editing the formula. Formula has no tabbed UI, so impress tabbed bar is not replaced with formula's tabbed bar (like other object types). It's classical bar is shown under the impress tabbed bar. The bug is impress tabbed bar isn't hidden.
Note: it happens on all modules.

My take: reopen bug 121484 and make this a duplicate. Andreas, do you agree?
yes that's fine
