Windows resize problem

Hi all,

I would like to know your opinion on this issue:
In Ardour 6.9.0 I can’t resize windows as desired (plugins and Ardour itself).

For example, I have a project with these plugins:
Vitalium, BYOD, SimpleScope.

The Vitalium GUI is not resizable (in the menu, the “resize” option is frozen).
BYOD, if I try to resize it with the mouse by dragging the three striped bars bottom right of the plugin itself, it doesn’t resize.
SimpleScope also doesn’t scale, using the mouse.
Ardour’s Editor windows itself I can’t resize.

This my configuration:
Ardour 6.9.0~ds0 “After Bach” (rev 6.9.0~ds0-1build1) Intel 64-bit (from repository)
Ubuntu 22.04.1

This is Ardour configuration:

Thanks for any advice.

I guess your UI scaling is too high, try to fiddle with the parameter in the preferences…

Hi, thank you.

If you meant to decrease this parameter: “User Interface Size and Scale” in Ardour Preferences, the only effect is to make the writing smaller.
Instead, in practice I would like to make the plugins windows smaller, so that they all fit, but they cannot be shrunk.
(Some at most can be enlarged to full screen, but cannot be shrunk).
Also I would like to shrink the Ardour editor window so that other windows of other programs fit on the same screen.
That’s what I meant by “resize windows as desired”.


Plugins provide a minimum size parameter to the plugin host, and will not allow shrinking smaller than that in order to keep all the controls visible. I do not know if there is a way to display the minimum size sent for each plugin and verify if they are indeed currently at minimum.

Thank you.

To clarify, this is the minimum size of the BYOD plugin:

This is the minimum size of the Simple Scope plugin:

The Ardour editor window, if I press the middle button at the top right, only shrinks about 10%.
It would be useful to be able to tile another window of another program, but it doesn’t fit… :slight_smile:
