GNOME Bugzilla – Bug 772597
Blank thumbnails after scrolling
Last modified: 2017-08-04 05:40:06 UTC
When scrolling through thumbnails (left side sidebar) of a PDF or PostScript document, sometimes all thumbnails are invisible. The thumbnails sidebar looks as if it was empty. Steps to reproduce: 1. open any document with many pages (more than 8…12) 2. scroll in thumbnails sidebar for some time What happens: Sometimes, the thumbnails sidebar looks empty What should happen: On a multi-page document the thumbnails sidebar should never be empty Additional info: I see this bug with any PDF document (~100 documents tested) with more then ~10 pages so you can scroll in thumbnails sidebar. I also have seen this bug with PS documents. This bug is present on both X11 and wayland GDK backends. This bug is not a recent regression, it was present with 3.20 and afaik 3.18 too. This bug is present with and without animations enabled. This bug is not present when scrolling on the main view using mouse wheel, PgUp, PgDown, arrow up, arrow down keys. This bug is not present when scrolling on thumbnails sidebar using PgUp, PgDown, arrow up, arrow down keys. Only happens with a scroll wheel. Affected versions: evince-3.22.0-1.fc25.x86_64 poppler-0.45.0-2.fc25.x86_64 gtk3-3.22.1-1.fc25.x86_64 glib2-2.50.0-1.fc25.x86_64 Probably related: https://bugzilla.gnome.org/show_bug.cgi?id=740331 https://bugzilla.gnome.org/show_bug.cgi?id=701537
Some observations: * When switching to another application (evince loses focus) and then back (evince gets focus), thumbnails reappear again on switching back. * When using the Gtk+ Inspector on the GtkIconView, icons immediately reappear again. I can't reproduce this misbehavior with other "GtkIconView"s in e.g. gnome-documents, gnome-photos. Might still be a Gtk+/Gdk issue though.
One way to get the thumbnails to show up again is to move the pointer to the main document widget, and then back to the thumbnail pane. Each thumbnail will appear as the pointer moves over it.
Thanks for taking the time to report this. This particular bug has already been reported into our bug tracking system, but please feel free to report any further bugs you find. *** This bug has been marked as a duplicate of bug 701537 ***
Are you sure this is a duplicate? The other bug seems to require the use of full screen mode. I experience this bug with every document, and never use full screen mode.
I could be wrong, but yes, I think they are the same bug.
