Open nautilus, change to a directory that overflows the headerbar space for breadcrumbs. Scroll on the headerbar to move crumbs left / right. Actual results: does nothing under wayland. Expected results: moves crumbs to left / right under X. This might be another instance of mutter not passing on scroll events correctly, but that is just speculation on my end. Version-Release number of selected component (if applicable): nautilus-3.18.0-1.fc23.x86_64 gtk3-3.18.1-1.fc23.x86_64
This still doesn't work with gtk3-3.18.2-1.fc23.x86_64 and nautilus-3.18.1-1.fc23.x86_64. Any chance this will get fixed - as it is really annoying.
I can reproduce this.
This issue has been closed upstream for nautilus and gtk+ 3.20. It can be closed now.
