faxe You're not alone! I've been encountering this behaviour since yesterday, and it began once I updated to the latest Vanadium release, 134.0.6998.39.0 Stable
. Like how you described, closing Incognito tabs via the "Close all Incognito tabs" notification causes the home screen / launcher to hang for several seconds. Swipe attempts are met with a "Processing Notification" notification pill.
After some experimentation, it seems that this behaviour is only occurring when Vanadium has first been closed, without closing Incognito tabs first. If I have Vanadium open, and tap the "Close all Incognito tabs" notification, there's no issue. If I go to the home screen, leaving Vanadium open, also no issue when tapping the notification.
However, if Vanadium is open, and I close Vanadium by way of tapping "Close all" in the app switcher, then tap the "Close all Incognito tabs" notification, this issue presents itself, causing the home screen and app launcher to hang with "Processing Notification" appearing.
