From acb0065cc7e4ee849cc87ce72e46b05a61370c43 Mon Sep 17 00:00:00 2001 From: Tang Haixiang Date: Thu, 25 Feb 2021 18:05:17 +0800 Subject: xcb: Update _NET_SUPPORTED when the window manager changes it MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In some cases, the application may start before the window manager, and in some window managers _NET_SUPPORTED may be changed. These situations will cause the _NET_SUPPORTED value obtained by Qt to be inconsistent with the window manager.
