Logspam: [WARNING] System.Taffybar.WindowIcon - Failed to load icon from filepath vscode

[nomeata]

Taffybar works mostly fine, but it fills the log (e.g. the user journal) with messages like

[WARNING] System.Taffybar.WindowIcon - Failed to load icon from filepath vscode
[WARNING] System.Taffybar.WindowIcon - Failed to load icon from filepath @joplinapp-desktop

whenever such applications are open and I do something like switching virtual desktops.

It seems to affect those applications that ship their icon in share/pixmaps and not share/icons/….

An icon is shown, though. Maybe taffybar tries multiple ways of retrieving an icon and prints a warning if some methods fail, but later succeed?

The frequency of the messages also make we wonder if taffybar happens to be searching for and loading the icon very often, instead of just once when the program in question is started.

Version information

This is taffybar 4.0.3 installed from nixpkgs 25.05 on NixOS.

Yes, taffybar falls back to ewmh icons when the icon specified in the desktop file does not work.

I'd need to double check the code, but I know that it at least attempts to avoid doing this for icons where the icon occupying a particular "spot" in a workspace is the same. This is something that is a little tricky to get right though, so we do err on the side of refreshing everything.

I paid a bit more attention, and I get five lines

[WARNING] System.Taffybar.WindowIcon - Failed to load icon from filepath vscode
[WARNING] System.Taffybar.WindowIcon - Failed to load icon from filepath vscode
[WARNING] System.Taffybar.WindowIcon - Failed to load icon from filepath vscode
[WARNING] System.Taffybar.WindowIcon - Failed to load icon from filepath vscode

even when just changing focus between two windows. Not sure if that’s intentional.
