Comment 5 for bug 1655398

There are some bugs reported to xfce4-screenshooter about copy to clipboard not working for large resolutions:
https://bugzilla.xfce.org/show_bug.cgi?id=13342

https://bugzilla.xfce.org/show_bug.cgi?id=10426
https://bugzilla.xfce.org/show_bug.cgi?id=12704

gnome-screenshot is also affected if started with -c flag or in interactive mode if you press the copy to clipboard button then close the app before pasting.
At first I thought it was something related to gtk_clipboard_set_image, but this problem doesn't happen when running /usr/lib/gnome-settings-daemon/gsd-clipboard instead of xfsettingsd.
