+Subject: [PATCH] Fix crash when setting blur effect
+
+Basically to use QWidget::windowHandle() to get a QWindow*, we need to first
+set the Qt::WA_NativeWindow attribute on the QWidget. See:
+https://phabricator.kde.org/D23108
+
+BUG: 439871
+FIXED-IN: 21.12
+(cherry picked from commit a6b2bd539162b39191e827566b656bd97266ffad)
