Additional context
I noticed that this bug is tied to hide_window_decorations. When set to yes the bug is present. When set to no it is not.

kitty does not resize itself in response to window system events, this will be your window manager's doing.

@kovidgoyal i was just wondering because it was depending on the hide_window_decorations option.
Thanks for looking into this anyway 👍

Probably you are on GNOME, causing all these issues with their insistence on CSD. See the open issue about it. #3284

THis is tracked in #4802
