long startup - might be graphical problem

Embedding output containing references to kscreen and xrender that I have not seen before - just in case something curious and unknown to me happened during update of a couple of days ago.
Not that I am wont to study the output of journalctl - I’m sure it has a fascinating history - and perhaps all this stuff is there at every boot.

But in the offchance this is new could someone translate it?
Symptoms = long wait at black screen with flashing cursor in upper right hand corner and THEN there it was my graphical interface with login screen appeared. Very long wait though, very long.
Graphics card is propietary nvidia driver 340.xx series fully updated.

best wishes,
