Public bug reported: On Ubuntu 21.04,since around 01 July 2021, Alt-Tab works as usual for a while after logging in, but then stops entirely (that is, it does nothing; the switcher overlay fails to appear, and switching between windows does not work). I made _no_ configuration change, and Alt-Tab continues to be configured in the keyboard shortcuts settings as usual.
This has been described by other users here: https://askubuntu.com/questions/1349544/alttab-stops-working-after-a -while-in-ubuntu-21-04 There seems to be some possible connection to Thunderbird in particular, and the fact that in the left-hand-side launcher (?) / favourites of the Ubuntu desktop, the Thunderbird icon starts behaving strangely, e.g. does not show the open Thunderbird windows when clicking on it ... while other applications work. ** Affects: ubuntu Importance: Undecided Status: New ** Tags: bot-comment -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1934527 Title: Window switching with Alt-Tab stops working after a while To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1934527/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
