Question/request: Is there a way to keep aspect ratio when resizing the window manually ? (original) (raw)

I've tried to search about it, but is there a way to keep the aspect ratio of the window, when I manually resize the window (meaning I exclude the single clicking for full-screen resizing, whether by keyboard or by mouse) ?
This way the window of ScrCpy will fit nicely with the content it shows (again, I'm excluding the scenario of full screen).

I mean using this:

I want to avoid the black parts around the content.

Maybe like some video players (I use Media Player Classic), we could use CTRL key while resizing, to force staying on original aspect ratio?
Or force it by a flag?
Or both?
