** Description changed:
- Ubuntu 22.04 development fully updated as of time of this report.
+ Impact
+ ------
+ On a fresh boot, as soon as you open some applications and do the up touchpad
gesture to enter the application grid and then back down to return to the
desktop, journal spits out js stacktrace. If you don't trigger the crash then
try opening and closing an app and trying again.
- On a fresh boot, as soon as you open some applications and do the up
- touchpad gesture to enter the application grid and then back down to
- return to the desktop, journal spits out js stacktrace. If you don't
- trigger the crash then try opening and closing an app and trying again.
+ Test Case
+ ---------
+ 1. Install the update
+ 2. Open a terminal and run journalctl -f
+ 3. You may need to wait a few moments for some background tasks like
NetworkManager or PackageKit to finish what they're doing. The journal should
be fairly quiet before proceeding.
+ 3. Open another app
+ 4. Perform the 3 finger swipe up gesture until the app grid displays then
swipe down to go back to the desktop.
+ 5. See journal for gnome-shell errors like seen below.
+ 6. If nothing happens try opening an app, closing it and try again.
+ What Could Go Wrong
+ -------------------
+ This is fixed in gnome-shell 44.1. See LP: #2020277 for more details.

+ Sample stacktrace
