The mouse stops working after trying to take an area screenshot in some apps on Xorg

[Andrey Plaksin]

[ Impact ]

Mouse stops working after taking an area screenshot

[ Test case ]

1. Open Chromium browser.
2. Go to the page with the form in which there is a standard browser drop-down menu (form select)
3. Open it
4. Try to take a screenshot with the keyboard shortcut: Ctrl+Shift+PrintScreen
5. Try to switch between applications using the panel and check the operation of the mouse in other applications besides browser (in my case Slack)

[ Regression potential ]

Grab events don't happen or pointer isn't ungrabbed when required.

[Brian Murray (brian-murray)]

The verification of the Stable Release Update for gnome-shell has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

[Daniel van Vugt (vanvugt)]

It looks like we forgot to fix focal so there are still bug reports there.
