Description Jean Abou Samra 2023-05-04 08:03:48 UTC 
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?
Comment 4 Jean Abou Samra 2023-05-18 14:51:15 UTC 
Could you advise on how to run Emacs under X11?
