I am using Impress in LibreOffice 220.127.116.11, German language on a Debian 8.2 laptop. In the Format - Styles and Formatting window, the Fill Format Mode is not working: I can select the button, but as soon as I move the courser to the slide part of the window, the courser’s shape does not change, as it does for example in Writer or Calc. Therefore, I cannot assign a different format style to any text box etc.
I checked, I have the same problem in LibreOffice 18.104.22.168.
I would be happy about any hints. Thanks in advance!
