This is exactly the same behaviour I am seeing, although I do not
have to leave libreoffice. Just now, I was working in libreoffice
when I noticed the fan going crazy, and checked top and strace to
find oosplash doing the poll-ad-infinitum described in #636873.
Using lsof, I could not map the file descriptor to anything useful.
It seems that some condition — which we do not know yet — puts
libreoffice into an infinite loop. This loop has two consequences:
1. While running, libreoffice remains usable while the loop churns
the CPU and eats the battery.
2. When shut down, the loop prevents libreoffice from exiting.
Hope this is useful additional information.
Cheers,
