The root cause of the bug is a classic case of removing elements from a linked-list while iterating over it unsafely, during the composition rendering pass. [ Test plan ] 1. Spawn many notifications: $ for run in {1..20}; do notify-send foo; done 2. Open the calendar menu 3. Click "Clear" 4. Verify that all notifications were dismissed 5. Verify that GNOME Shell did not crash and log you out [ Where problems could occur ] mutter is the component of GNOME driving the screen and inputs, and thus is a critical component of Ubuntu Desktop. Problems would manifest with the desktop rendering incorrectly or crashing. The side-effects being very evident and the patch being trivial make this upload a low risk for regressions.
