+Subject: [PATCH] Disable toplevel fixed positions on Wayland
+
+Given that the wayland protocol does not have window positions a recent
+change to Qt development branch avoids having a mismatch of positions
+and tells client code the window is at the topleft of the screen. This
+fixes multiple bugs.
+
+Unfortuantely this breaks a few usages within plasma where a
+side-channel sends that absolute positional information over a bespoke
+protocol. Currently we proxy this all through QWindow geometry where the
+new Qt behaviour will throw is askew.
+
+Whilst our longterm plans are to find future options away from the
+plasmashell protocol we may as well have our Qt6
+build work given the patch is trivial and harmless.
+
+It also allows for potential backporting if our software is
+already secured against issues.
