+Subject: [PATCH] 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.
+
+Fixes: QTBUG-91396
