From 817655fa798fc2d640b4db006df229c335e02c3b Mon Sep 17 00:00:00 2001 From: Vlad Zahorodnii Date: Tue, 27 Sep 2022 22:05:07 +0300 Subject: [PATCH 44/51] Client: Handle zwp_primary_selection_device_manager_v1 global removal The zwp_primary_selection_device_manager_v1 global can be withdrawn if the compositor disables the primary selection, i.e. middle click to paste selected text. QtWayland needs to handle that; otherwise the app can crash.
