Version: 7.6.3.2 (X86_64) / LibreOffice Community Build ID: 29d686fea9f6705b262d369fede658f824154cc0 CPU threads: 4; OS: Windows 10.0 Build 19045; UI render: Skia/Vulkan; VCL: win Locale: ru-RU (ru_RU); UI: en-US Calc: threaded Create New text documwnt in Writer - Format - Watermark... - in the field "Text" enter any text you like, for example, "AnyText" and press Ok button. Now wee see watermark on our page, but list of Undo operations (Ctrl+Z) is empty and we can't Undo adding a watermark. But Writer realizes that changes were done in the document (file can't be closed without a dialog box with a suggestion to Save changes to document).
I can confirm this bug. Also present in the 24.2 and 24.8 series.
What I found to be strange is that even if I type some text, and add a watermark, the undo is not available even for text, which is what I think is more critical, maybe I have deleted some text before, and I need to undo, at least the text part.
