Mouse not changing focus to application or workspace after system update [closed]

Hello,

Yesterday I did an update on my Arch Linux and this broke i3. Now, whenever I move the mouse over to a different application or even to another workspace, the focus doesn't change. However, if I reload i3 (mod+Shift+r), it goes back to normal for a few seconds, and then stops working. Changing focus with the keyboard works as expected. Below is Pacman's log.

Any help is appreciated. Thank you.
