+Subject: [PATCH]  Client: do not take decoration shadows into account when placing popups
+
+The anchor rectangle is relative to the window geometry, which according
+to xdg-shell specs shouldn't include invisible portions like shadows.
+This causes all popups be wrongly positioned when drop-shadows are used.
