Public bug reported:
Since my upgrade to 20.10 I am sometimes seeing the keyboard becoming
unresponsive (or very slowly responding) in some applications. At the moment
emacs is in this state - menu events in emacs are fine. I've also seen this
behaviour in konsole and firefox. I think the loss of keyboard happens after
closing a window (but not always), so far I don't have a recipe for replicating.
I've seen bug #1912670 but I'm running plasma (and kde 5.74.0) and my mouse
isn't affected - and the current hypothesis on that one is that it is xfce
related.
In spite of keyboard not working, here I am typing (in the browser) without a
problem. Sometimes when it is unresponsive I'm seeing a c5sec delay before the
keyboard event is acted upon rather than nothing at all happening.
lsb_release -rd
Description: Ubuntu 20.10
Release: 20.10
I've just suspended the desktop and on un-sleeping the problem is still
present.
There's no messages in stdout/err for the current emacs session. CPU
doesn't look terribly busy. Suggestions on how to debug this are
welcome!
