Missing/default icon for Wayland window navigation (alt+tab) menu

mrgabr · July 31, 2026, 8:51pm

Steps to reproduce

Install Obsidian 1.13.4 from any source on KDE Fedora 44 Linux.
Open Obsidian.
Hit alt+tab to bring up the window navigation menu.

Did you follow the troubleshooting guide? [Y/N]

Yes.

Expected result

Obsidian’s window has the normal icon.

Actual result

Obsidian’s icon in the alt-tab menu is a yellow circle with a W (which I assume is the fallback Wayland app icon). The icon on my task manager and applications list are still the correct icon.

Incorrect taskbar icon on KDE Wayland due to app_id mismatch after #534

### Description After updating the Flatpak to the build that enables Wayland by… default (#534), Obsidian displays the generic Wayland icon in the KDE Plasma taskbar instead of the Obsidian icon. The icon file itself exists and the exported desktop entry is valid. The problem appears to be a mismatch between the Wayland `app_id` reported by the window and the Flatpak desktop file name. ### Actual window properties Obtained from KWin: ```text caption: <note> - <vault> - Obsidian 1.13.4 resourceClass: md.Obsidian desktopFileName: md.Obsidian ``` ### Flatpak desktop entry ```text /var/lib/flatpak/exports/share/applications/md.obsidian.Obsidian.desktop ``` Relevant fields: ```ini Icon=md.obsidian.Obsidian StartupWMClass=obsidian X-Flatpak=md.obsidian.Obsidian ``` The Wayland window reports: ```text md.Obsidian ``` but the desktop file/application ID is: ```text md.obsidian.Obsidian ``` Since these values do not match, KWin cannot associate the Wayland window with the desktop entry and falls back to the generic Wayland icon. `StartupWMClass` does not appear to help for the native Wayland window. ### Steps to reproduce 1. Use KDE Plasma on Wayland. 2. Install or update `md.obsidian.Obsidian` from Flathub. 3. Launch Obsidian using its desktop entry. 4. Observe the generic Wayland icon in the taskbar/window switcher. ### System information ```text OS: Fedora Linux 44 KDE Plasma Desktop Edition Session: Wayland Obsidian: 1.13.4 Flatpak app ID: md.obsidian.Obsidian Flatpak commit: d096dd936d122bd97ab6c1a99a5513a0028f8bf6a3cae9f4f2421ff62adc6821 Commit subject: Switch to using Wayland by default (#534) ``` ### Expected behavior The Wayland `app_id` should match `md.obsidian.Obsidian`, allowing KDE to resolve the Obsidian desktop entry and icon. ### Disclosure The initial root-cause investigation and collection of the window metadata above were performed by an AI agent. However, the visible icon issue itself is straightforward to reproduce manually by following the steps above.

The tarball is here - it’s what the Arch package (and probably Fedora as well) use. In the current version there’s a mismatch between what StartupWMClass in the .desktop file says, and the actual class the window gets. I don’t see where that .desktop file comes from - it’s not in the tarball itself - but my workaround was to copy the system desktop file to ~/.local/share/application and adjust it:

This isn’t a bug in Obsidian, IMO.
