When using "Ctrl-<left arrow>" or "Ctrl-<right arrow>" in order to put the Emacs window side-by-side with another application, it has a black margin that impinges on the other application. Also, when using the Super key to enter the app overview, you can also see such margins on the top and on the bottom. Screenshots attached. This is on Fedora 38 with GNOME. This is usually not seen, Reproducible: Always Steps to Reproduce: 1. Open Emacs. 2. Press Super+Left. Actual Results: Black margins. Expected Results: No margins.

You are running wayland with GNOME, right? If you can try it with X11 easily, could you please try to reproduce it with X11 as well?
Could you advise on how to run Emacs under X11?
I just checked it on F39 and rawhide (wayland and X11) and I can't reproduce. Is it emacs 29.1? Could you also please try "emacs -Q" and see if it behaves the same?
Well, I upgraded my system multiple times across the life of Fedora 39, and I don't have the problem anymore. This bug can probably be closed.
I actually was able to reproduce it a few days ago on Fedora 39. I've been messing with various DE installations and I can see it on KDE+Wayland. Let me collect some more info and I'll post it here during a couple of days.
As @jean mentioned the issue can probably be closed. I think I confused the bug initially reported with something else (see attachment below). I've found that emacs library called spacious-padding is causing issues in my emacs when I create split buffers. But then I just double checked the screenshot initially attached and turned out I was chasing the wrong issue.
