+Subject: [PATCH] Keep toplevel windows in the top left corner of the screen
+
+Cherry-picked from commit a46795a2. Fixes https://bugs.kde.org/show_bug.cgi?id=436016
+------------------------------------------------------------------------
+We can't know the actual position of a window on the screen. This causes
+an issue when Widgets try to position a popup/menu absolutely and keep
+it on the screen when the screen geometry doesn't include (0,0).
+Instead report their positions always as the top left corner of
+the screen that they are on.
+This new behavior can be disabled for qt-shell or via an environment
+variable by users that rely on the old behavior.
+
+Fixes: QTBUG-85297
