Not sure if window trimmings is the right word, but on the outside of the window there's a wooden like border (not sure what material exactly, but doesn't matter).
What I did notice however was that some windows had flush corners and others didn't. I've attached a photo showing the corner for 3 different windows of the house (one having flush corners). Not sure what I think about it or if I care that they are different, but seems weird to not keep it consistent. I like consistency. Will have to have another look around the house some day to see what I think and whether it is worth doing anything about.
Is this common? Should I care?
