    Description

      Sometimes Ubuntu 24.04 x64 targets:

      • ubuntu-24.04-x64-x11-tests
      • ubuntu-24.04-x64-developer-build-x11-tests

      have failed with 200, 500 or even 600 failing tests with QDEBUG prints flooding in 60,000 - 80,000 lines.

      Found similar amount of failings from Ubuntu 22.04 target:

       

      More comparable tests with same failings when target has multiple tests failing:

      Update to description from a comment at 21.1.2025 which described found rootcause better:

      Managed to reproduce this issue in CI with debug VM, and GUI is no longer workable:

      Host logs got insight about what is causing the crash and we might have possibly found the rootcause, thanks to tosaario

      Ubuntu 24.04 has gnome-shell 46.0 which has a bug which is fixed at 46.1. Bug report created by Toni, more info from there:

      By checking gnome-shell packages, it seems that Ubuntu 24.10 already has gnome-shell 47.0:

      Side notes:

      • Logs showed also
        • "Window manager error: Another compositing manager is already running on screen 0 on display “:0”."
        • "Start request repeated too quickly"
      • Not sure if those could give any workaround to recover from this, before fix is backported to Ubuntu 24.04
