I just experienced it too last week. I'm using Ubuntu since 2015.
Current mouse (trackball) I used from the beginning of 2020. It works with no
issue with Ubuntu 18.04. Issue occurred just after last Ubuntu update (middle
of August).
Whats funny when I have my mouse/trackball plugged in I have this issue also
with touchpad.
When I remove mouse USB - everything works fine again.
Another thing is that when I plug in other mouse or trackball - the issue is
not present. It is just with single device.
I also tried with another laptop with Ubuntu 18.04 (without update) I
worked on it 2 hours - there were no issues. Then I just updated Ubuntu
and restarted that second laptop and... issue occurred also on the
second machine and again just after Ubuntu update. I'm mad, I love to
work with my trackball but I cannot now.
This behavior is so strange.
Also when I unplug my trackball and plug it agan it works fine for 30-60
seconds and then issue occurred again.

Title:
Focus gets stuck to a window - impossible to select other windows
Status in xorg-server package in Ubuntu:
Fix Released
Bug description:
Alright, terribly annoying bug that gets me to reboot several times a
day, but very hard to understand how to trigger it.
What happens: after some time of usage, you get "stuck" in a window. Idem
est, you can not select another window.
You can still click, select and drag in the window that has the focus, but
clicking on other windows, or on the panel, just doesn't work.
Notes:
- With window I don't mean "application window". For example it can only be
the page view in firefox, and you won't be able to click the buttons or the
URL field. It can also be the main text window in xchat, and you wont be able
to click in the user list or to change the chatroom.
- The click seems to be grabbed by the window having the focus, even if you
click outside of it. For example, using xchat, if the main text window has
focus, clicking and dragging in the user list will actually select text in the
main text window.
- Using xev, it seems that clics do not get passed to the correct window at
all (nothing received)
- I have no idea what triggers this as sometimes it will trigger alone - pc
works, I leave it for an hour, I come back, the problem is triggered
- Curious effect now: dragging and dropping to another window gives focus to
the window, and seems to be the only way to do so. For example if in firefox
the main page view window has the focus and I cant click the buttons, drag and
dropping text to the buttons gives the focus to the buttons, and I can't clic
the page view window anymore. Drag and dropping a button to the page view
window gives it its focus back
Additional info:
* Compiz disabled
* Intel graphic card
* Ubuntu jaunty - latest patches
* Using a laptop, with an USB mouse
HAL, xserver, I have no idea where to file this bug into. I hope it will be
fixed before the release, it is really terribly annoying :s
Please tell me if there is any other detail I can provide.
