01:57 zzxyb[m]: when a Wayland client selects a text, and then the cursor clicks on a blank area, does the client need to send zwp_primary_selection_off.destory to the Wayland compositor? Notify the compositor that primary_selection is empty
01:59 zzxyb[m]: currently see that gedit (gtk) sends zwp_primary_selection_off.destory, but Qt does not send it.
02:21 soreau: It's up to each client to choose behavior, the spec doesn't really say AFAICT
02:28 zzxyb[m]: yes, but each Wayland client implementation is different, which will cause some troubles
04:10 Company: zzxyb[m]: iirc Qt and GTK have treated primary selection differently forever - ie even on X11
04:12 Company: and if the primary selection should be cleared on unselect was part of that
05:04 zzxyb[m]: Indeed, for clearing the primary selection the behavior is different
