There is one important step for reproducing this bug, not only in
gnome-terminal, but also in nautilus and gedit:
* open multiple tabs
* !!! reorder one of the tabs !!!
* leave pointer hovering over one of the tabs
* observe tooltip appearing, and cursor changing to reflect loss of focus in
Apologies, I was unable to access the machine for testing this until
recently, so have been unable to run the test kernel in #21.
Revisiting this problem again on the same machine with kernel 5.13.0-27
I still see it as behaving as originally reported, so I expect neither
the patch nor proper fix
Thank you for following up.
I have managed to complete a commit bisect of the Ubuntu kernels and can
confirm that the first bad commit is

ALSA: hda: call runtime_allow() for all hda controllers
BugLink: https://bugs.launchpad.net/bugs/1876765
Last known working kernel: 5.4.0-33, next installable Ubuntu kernel
5.4.0-37 introduces the bug.
I have tested that saving "options snd_hda_intel power_save=0" to a file
under /etc/modprobe.d and rebooting to a kernel from -37 onwards is a
valid workaround.

Ignore my last comment about last known working kernel, I've rebooted to
5.4.0.40 and I still see this issue, will try and do more testing on
kernel versions to see if I can find where it changes, and will also
look into the power_save options.

To add to #9, as well as the headphones being detected after running
alsa-info, I can confirm that they still work as expected after
detection.
As this may be a bug introduced by a kernel change, the current kernel
running is 5.4.0.42.45 (generic, x86_64), whereas the previous one I was
running
The output of cat /proc/asound/card1/codec#0 after running alsa-info
differs slightly to that included within the alsa-info log itself (in
#8):

> Converter: stream=5, channel=0

Then after the fresh boot, I connected the headphones, verified no
sound, then re-ran alsa-info which gave the following attached log.
** Attachment added: "alsa-info log with headphones plugged in"
For reference, after a fresh boot without headphones plugged in on my
machine, the alsa-info command gives the attached output.
** Attachment added: "alsa-info log fresh boot with no headphones connected"
After running alsa-info, it appears that the headphones were detected
and started to show in Settings GUI, also showing in the attached pacmd
list report.

For comparison, a log from before I plug in the headphones (after a
fresh boot)

As requested - after a fresh boot, and plugging in headphones and
verifying that there is no sound from them.

And a log from after I use pavucontrol to manually enable the 17h audio
controller while the headphones are plugged in, and confirming that they
do work as they used to.

I see a similar problem with incorrect partition information in gnome-
disk-utility. I am not sure if it's exactly the same as the OP's issue
as in my case the problem is solely triggered by running GParted, and
not by the deletion/modification of partitions as mentioned by the OP.

Just got this when dragging a file from file-roller to a nautilus window
on Ubuntu 16.04 64-bit. Nautilus would scroll its window up and down in

Interesting that the last person mentioned Caja - there is potential
progress in narrowing down where the problem lies in their issue tracker
(https://github.com/mate-desktop/caja/issues/528).
Nautilus, Caja and Nemo all exhibit this same behaviour. In the Caja
issue tracker zaps666 suggested
Still a problem in 16.04 LTS - constantly burning 20% CPU on idle.

Taking out "nolapic_timer" from grub options has allowed pulseaudio to
