** Description changed:

- I have some mkv files with pathologically large (50MB!) coverart pngs
+ I have some mkv videos with pathologically large (50MB!) coverart pngs
  attached inside them. If I play one in mpv, the entire desktop becomes
  unresponsive. By SSHing into my otherwise unresponsive system, I can see
  that gnome-shell is at 100% cpu load.
  
  This can be reproduced by creating a large png (convert -size 1500x2000
  xc: +noise Random noise.png), use mkvtoolnix to open some preexisting
  mkv file, go to the Attachments tab, add the noise.png file, and "start
  multiplexing" a new "evil" mkv file. Play that mkv file in mpv. The
  ~20MB video that this produces should only freeze your desktop for a few
  seconds.
  
  Doing the same with a dimensionally-large but low-entropy (6000x8000px
  all white ~20KB) does not appear to cause any issues. Doing it with a
- 50MB png seems to be enough to freeze the desktop for ... as long as
- I've been willing to wait. Hours.
+ 50MB png (3000x3000 should do it) seems to be enough to freeze the
