I am running ubuntu on a 28 inch 4k (3840x2160) Dell display. I want to enable 1.5x display scaling like it was possible to do in previous versions of ubuntu (unity) or at least make the window title-bars larger. However the 200% scaling would make it equivalent to a 1080P display which would be a little large for this resolution.
Chrome and VSCODE so far have been able to get around this, possilby because they are based on electron? I have attached a screenshot showing the settings and window size.
