With Wayland being the default in Fedora 25, I would not be surprised
if this is causing the issue.  As Scribus is written in Qt, support for
Wayland is not likely to be the same at the GNOME/GTK libraries.

I wonder if you could compare this on Fedora 25 with a KDE or other DE
without Wayland ?

Thanks,
Peter

I have Fedora 23, and I am curious how Wayland works in Fedora 25 because I have a lot of X11 applications and Fedora 23 is near EOL.

Luya -- did the slowness happen after upgrading to Fedora 25 or after updating to specific SVN revision?

On Fedora 23, I think that can I select X or Wayland based desktops when I log in. Does Fedora 25 also give that option to let you check quickly if the issue is Wayland or Scribus?

If the issue is Scribus, can you use svn bisect to locate the revision that causes the problem? http://search.cpan.org/dist/App-SVN-Bisect/bin/svn-bisect

It looks like Qt 5.7 will have an option to access Wayland directly. http://blog.qt.io/blog/2016/06/13/new-compositor-api-qtwayland/ (New Compositor API for Qt Wayland) https://wayland.freedesktop.org/qt5.html (Qt 5 on Wayland) https://wiki.qt.io/QtWayland (What is QtWayland?)
