[orca-list] Ubuntu Mate 22.04 getting stuck

[Rastislav Kish <rastislav kish protonmail com>]

Hello list,

after upgrading to Ubuntu Mate 22.04, I noticed an interesting problem.

After closing certain applications, the keyboard navigation seems to get
stuck.

I'm not able to switch windows, do tab navigation and not even press
Alt+F2 to restart orca, when pressing backspace in where I expect to be
a dialog, no beeping is played so I assume it wasn't even displayed.


I don't have proofs yet whether the keyboard or possibly sound is
malfunctioning.


But, one thing is for sure. After waving the mouse cursor a bit via my
touchpad, everything usually just starts working again in few seconds.

Except one case, I don't even need to click on anything, just moving is
enough.


Applications where this usually happens are VLC, but browsers tend to do
it as well, I didn't notice any common sign of them.

What makes debugging particularly difficult is hard reproducibility, it
happens just from time to time, seemingly randomly.


Did anyone notice similar behavior?

Did you find out the cause, or possibly a workaround?


Thanks!


Best regards


Rastislav
