Audio MIDI settings windows empty

i’ve got a problem with the audio settings window :when i open the window, it’s empty
i’m using ardour 8.12.0
thank you for your answer

Can you provide a screenshot? And maybe some basic information about your system, like what operating system you are running on? Thanks

Some Linux systems with non-standard window managers can suffer from this.

Ardour Preferences > Quirks > Allow to resize Engine Dialog can help in those cases.
