This is a good example of how things evolve in the Linux world. Xorg has been dated for a long time and has outlasted many attempts to replace it. Wayland seems to have major momentum, but a major change like this does not happen without a period of sorting out the issues.
If enough of the other upstream solution suppliers buy in and support Wayland, things will eventually re-stabalize ( to the extend "stable" applies in the open source world ).
However, one of the outcomes of this type of evolution is that the applications developed for "X" which have reduced or completely lost their development community will be left behind.
Looking at the "Shutter" website it appears that the last release occurred more than three years ago. It may be that you would be better off looking for an alternative solution that has active development activity.
Its too bad that a perfectly functional solution fades away, but that is a characteristic of a world based on source code compatibility (open source) rather than binary compatibility ( Microsoft??).
The above is my perspective on the Linux world we live in, others may completely disagree and that is another example of the joys of the "Open Source" world.
PS, Or you can continue to run "X" in Fedora, its still available at the login prompt.
