i3-wm: No resize event when broot started together with a terminal emulator

[gl4eqen]

Describe the bug When broot is started together with a terminal emulator (tested with alacritty and xterm) on i3-wm (could not reproduce the bug on dwm) it does not fill the terminal emulator's window.

To Reproduce

• Start terminal emulator together with broot

$ alacritty -e broot
# or
$ xterm -e broot

Expected behavior broot should fill terminal emulator's window.

Configuration (please complete the following information):

• broot version: 1.3.1
• OS: Arch Linux
• DE: Regolith Linux (i3-wm based), problem also reproduced in vanilla i3-wm
• Relevant configuration items
  • Problem does not seem to be dependent on a configuration of aforementioned programs

Additional context None

Precision: As seen together in the log, broot doesn't receive any resize event in this configuration.

EDIT: Yes, forgot to add broot.log. Fixed now.

I reproduce this exact problem. It looks like i3 silently resizes after broot finishes loading.

A tested workaround is to delay broot launches with a script containing a sleep.

Broot could incorporate a configurable delay before checking again the dimensions but I'm quite reluctant to add such a hack at this point as it really looks like a i3 bug.

@Canop

it really looks like a i3 bug.

It's interesting because it seems like broot has issues with this initial resizing in sway as well. It looks like sway is so compatible with i3-wm, it also implements original bugs. Unless this resizing problem is actually part of i3-wm design. Hmm.

I cannot repro on my side when using Manjaro + i3, broot seems to fill up all space normally
