Public bug reported:
Whenever I alt-tab from one window to another, once in a while (very
erratically, but often enough), the new window doesn't seem to retrieve
the keyboard focus, so that whenever I start typing in a text field of
the new window, it actually writes - and other keyboard related
behaviors such as validating a message with Enter - in the *previous*
window.
I'm unsure since when exactly this occurs, maybe last system update. I'm
(almost) sure the behavior wasn't there when I first installed 24.04
LTS.
This is a security vulnerability because if I type some credentials, if
I'm not cautious enough, I might type them somewhere public such as a
group chat instead of where it belongs.
NB: I use X11 instead of Wayland because Zoom Desktop Client fails to perform a
screen sharing with Wayland.
