TraceyC <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Severity|wishlist |normal --- Comment #4 from TraceyC <[email protected]> --- Another report has come in about this with more detail which confirms this is a bug. It has a trace of inotify which will be useful. Copying from the other report: SUMMARY When starting some electron applications all active Firefox Developer Edition Instances in the Icons-Only Task Manager get regrouped as normal firefox. The bug is triggered by any process that rewrites mimeapps.list (confirmed: Vesktop, MongoDB Compass, K8sLens). Electron apps that touch mimeapps cleanly or not at all (VSCode, Chromium, Microsoft Teams for Linux, Chromium-based PWAs) do not trigger it STEPS TO REPRODUCE 1. Install both firefox and firefox-developer-edition with their own distinct .desktop file and different StartupWMClass entries 2. Pin Firefox Developer Edition to an Icons-Only Task Manager and launch it. Confirm correct icon and grouping with the pin 3. Launch an electron App (Tested with Vesktop, MongoDB Compass, K8sLens) that rewrites mimeapps.list OBSERVED RESULT All active Instances of Firefox Developer Edition, that had the correct group and Icon before, get grouped as Stock Firefox with the default Firefox Icon in the Taskmanager. EXPECTED RESULT Nothing should change ADDITIONAL INFORMATION KWin correctly detects the application: qdbus6 org.kde.KWin /KWin queryWindowInfo on the affected window returns - desktopFile: firefox-developer-edition - resourceClass: firefox-developer-edition - resourceName: firefox A window rule with Force "Desktop file name = firefox-developer-edition" does not prevent the flip Moving /usr/share/applications/firefox.desktop aside makes the bug disappear entirely. Restoring it brings it back, even though firefox-developer-edition.desktop has a distinct StartupWMClass=firefox-developer-edition that exactly matches the windows resourceClass Running inotifywait -m ~/.config/mimeapps.list ~/.cache/ksycoca6_* before triggering the bug shows .config/mimeapps.list DELETE_SELF Trying to overwrite the Desktop Entry with a firefox-developer-edition.desktop file in ~/.local/share/applications did not change anything -- You are receiving this mail because: You are watching all bug changes.
