Subject: [PATCH 050/147] 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
Change-Id: I63c6934ad2538cdb9f05926b3748216bd0dcf04e
