Unrecognized parameter “quality” passed to the PNG saver

[andrey-bolduzev]

After upgrading to python 3.9, I can't seem to make it work. Running with -C now fails silently with nothing copied to the clipboard and a 0 exit code and running with a filename produces a uniform black png with this output (and also a 0 exit code):

(escrotum:23207): GdkPixbuf-WARNING **: 10:00:03.461: Unrecognized parameter “quality” passed to the PNG saver.

Is there anything I can do to debug the issue deeper?

I see this too. yay $(pacman -Qqo /usr/lib/python<version>) for each of 3.8, 3.9, 3.10, and a reboot did not fix it.
