Some app icons are not being displayed on wlr/taskbar

[Faugus]

I tried different icon themes.

Is there a way to fix that?

[faugus@archlinux ~]$ waybar -v
Waybar v0.9.24

I am also experiencing weird issues with icons not being displayed. It seems to be dependent on monitor configuration.

Odd workspace numbers are my left monitor, even workspace numbers are my right monitor. On the left monitor it works consitently, on the right monitor it doesn't. Except when waybar only displays on that one, then it works.

I am on version v0.10.0

How can we help to debug this?

[Faugus]

I only have one monitor and I only use one workspace, so that doesn't apply to me.

I'm using Labwc btw.

I am also having the same issue, 2 monitor and separate bar configuration on both of them. icons are disappearing randomly , one of the 2 monitor at random vscode is focussed, but icon is not there, but sometimes it shows. random behaviour

[isshin1]

seems like newly created windows are shown with icons, as when i reload sway, with waybar , the newly created windows before lose their icons as well.

Same multi-monitor problem on hyprland when dragging windows cross monitors

Also affected by this when using multiple monitors.

Edit: Moved to #3366.

I made its own issue, as I think the OP's issue is completely different (and may be related to icon paths or format) and they specified a single monitor setup.

Happens on latest (git) waybar and hyprland. Single monitor setup. And in my case, with only the icons, I can not click to focus the app with the missing icon. (Still can't tap on Firefox after fixing the icon. Sad.)

edit:

Saw this with waybar --log-level trace:

[2024-06-19 18:53:22.819] [debug] Task (0) overwriting app id 'unknown' with 'firefoxdeveloperedition' 
[2024-06-19 18:53:22.819] [debug] Task (0) [firefoxdeveloperedition] <amif> Loaded icon 'unknown' 

(It said overwriting app id 'unknown' with '??????' for all open apps, but some fail to load the icon so we get unknown.)

And so, setting this:

  // ✨ other wlr/taskbar options ✨
  "app_ids-mapping": {
      "firefoxdeveloperedition": "firefox-developer-edition"
  }
},

fixes it*. ( ref: #921 #1135 #1221 )

* check parantheses in 1st para
