Comment 62 for bug 1502263

A workaround, until shutter is fixed might be this flameshot snap package:
https://snapcraft.io/flameshot-app

You would install it like this:
sudo snap install flameshot-app

Also, I'm not aware of a snap packages for shutter itself, but I did come across this:
https://launchpad.net/shutter/+snaps

That may be a snap package for shutter, but I have no clue how you would install it. I tried this:
 sudo snap install shutter
 error: snap "shutter" not found

No luck.
