[Bug 1771313] [NEW] GNOME3 Scaling Won't Enlarge Audacity on 4K Monitors

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

I use 4k monitors at max resolution exclusively. Both my laptop and 2nd
monitor are 4K at 2160P resolution.

Although GNOME 3 allows desktop scaling at 200%, 300%, etc., it isn't
true desktop scaling; only minimal (and insignificant) portions of
audacity's user interface gets enlarged using GNOME 3 Desktop Scaling.

To use Audacity, I'd either have to drop resolution or use GNOME 3
Universal Access > Zoom feature. Neither of these options satisfies me.

The zoom option wouldn't be so bad, if you could smoothly alt-
scrollwheel-zoom, but instead GNOME3's zoom is terribly un-smooth and
requires multiple 3-factor-keystroke-combination shortcuts to activate
and control.

Desktop scaling a foolish idea, anyway. What would be better is "window
scaling", where you can scale each applications window separately. The
window manager should keep up with the last scaled-proportions of each
previously launched application.

Back around 2008, Mandriva released a desktop called Metisse that allowed (seemingly infinite) fractional scaling for each window! (much less is per monitor granularity) Here's a video of that in action:
https://www.youtube.com/watch?v=dxsUKX6xXyE&t=40s

To accomplish this, using Metisse, you'd simply hold down shift (or was
it ctrl) while resizing the window.

You could do almost anything to that window, and all your mouse actions
on that window would still work accurately no matter how you scaled it.
You could even do silly impractical things like turn the window up-side-
down, pivot it, push the left side of the window deeper into the
background than the right side, etc. And, all your interactions with
that window would still work accurately. It was amazing (and done on
Linux first -- 10 years ago).

When will the world catch up with what Metisse accomplished in 2008? It
was way ahead of its time.

Here's an academic paper on Metisse:
