this makes it work for me
LibreOffice under wayland won't successfully paste from the CLIPBOARD after the
PRIMARY selection is used to paste from another app into it.
I paste from PRIMARY and then immediately request the targets of CLIPBOARD:
selection_buffer_notify generates a GDK_SELECTION_NOTIFY event for this
CLIPBOARD request using selection_buffer_notify but sets the selection field to
PRIMARY from the passed in SelectionBuffer.
So the notification dosn't match in _gtk_selection_notify at the
info->selection == event->selection so the CLIPBOARD request is never satisfied
and times out.
The problem appears to be the cache used by
_gdk_wayland_display_convert_selection of gdk/wayland/gdkselection-wayland.c
where...
buffer_data = g_hash_table_lookup (wayland_selection->selection_buffers,
target);
...
g_hash_table_insert (wayland_selection->selection_buffers,
GDK_ATOM_TO_POINTER (target),
buffer_data);
So the buffer_data for the PRIMARY selection was cached and reused for the
CLIPBOARD selection. The attached patch "for for me(tm)" by just updating the
selection of the cached buffer_data to the requested selection on retrieval</pre>
