Description Olivier Crête 2016-12-09 23:03:43 UTC 
If I open a PDF document with annotation with GDK_BACKEND=x11, then annotations move up and down with the document when I scroll it. When I run it with GDK_BACKEND=wayland instead they just pop up on the top left and never move! I assume this is because annotation are toplevel surfaces while they should be subsurfaces, which I think corresponds to POPUP windows in GTK+.

Versions:
gnome-shell-3.22.2-2.fc25.x86_64
mutter-3.22.2-1.fc25.x86_64
evince-3.22.1-1.fc25.x86_64
Comment 1 Olivier Crête 2016-12-09 23:58:32 UTC 
Hmm, this is not as easy as I Though it would be. We really need the annotations to be subsurfaces, but the API to force a window to be a subsurface gtk_window_set_use_subsurface() is private.. And this isn't really a popup. Maybe it should be re-implemented as a GtkPopover ? That would also have a nice "pointer" to the right annotation.
Comment 2 Germán Poo-Caamaño 2017-09-27 14:15:56 UTC 
IIRC, we have talked about exploring the use GtkPopover for annotations.

Currently, there are additional issues. For example, in continuous mode, when changing the pages, the annotation windows flicker a lot, because they are either fully shown or not (it looks like they resist to disappear, if you know what I mean :-)

The flicker is also present when moving the page up or down.

I believe that any patch in that direction would be welcomed.
