I noticed a few mpv processes which were still running eventhough I hadn't opened these myself, it seems anki launches these (even though I haven't got any audio or video in my cards) but doesn't kill them after quitting.

Anki info:
Version 2.1.26 (2a0d40e1)
Python 3.8.1 Qt 5.14.1 PyQt 5.14.1

System info:
Operating System: openSUSE Tumbleweed 20200509
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.69.0
Qt Version: 5.14.1
Kernel Version: 5.6.11-1-default

System Mpv version: 0.32.0+git.20200501T204851.cae2ffb6eb-258.2

    If you kill them, start Anki, and close it again, are there any processes remaining? If not, under what circumstances are the processes not being cleaned up?

    I've done the following:
    1. Quit anki in a normal way (ctrl-q)
    2. Kill the remaining mpv process (by sending a signal from ksysguard, this shouldn't differ from sending a signal from for instance htop)
    3. Launch anki again without doing anything (I've tried the same with doing a review)
    4. Quit anki again normally
    5. No mpv processes remain and no extra mpv processes were spawned by anki.

    As you can read, I don't seem to be able to reproduce the bug at this moment, I will keep an eye on any remaining processes. I will be able to do more extensive testing once I'm done with an exam (learning for the exam using anki :)).

    Now that I think of it, the remaining mpv process might have been caused by the regex bug I reported here:

    I'll try to reproduce that later too, but if that's the case the bug wouldn't be that surprising given the ungraceful quit of Anki after the freeze.

    An unclean shutdown would explain it
