I do live in Seattle, but where I've previously lived the temperature routinely goes to -30F in winter and 95F in the summer, and for the reasons of previous lack of availability plastic windows were one of the first things people installed, including on e.g. 5-6ft square panels. Never heard of the problems with them, and never had problems with whichever ones I used. However in many places I lived (including with mild climate like SF) wooden windows never failed to have some wonkiness to them, and in one apartment when you closed the sliding windows too fast there'd be fresh wood shavings coming out :) Also just googling "vinyl window wrap" or deformation (I assume vinyl is what people typically call cheaper plastic?) I cannot find much of anything. On the other hand if you google for wooden windows or siding moisture/deformation/rot, you find plenty of advice and complaints alike. These physics seem to be reality defying, or they apply in some extreme conditions when comparing with the best possible wooden window... And I tried to avoid bringing up taste, even though I wanted to, but I guess I have to bite now. That actually gives me additional disdain for wooden-window-buying - yep, they are still popular because a significant fraction of the population still thinks that e.g. craftsman houses with "nooks" and 4-to-7ft sloping ceiling on the 2nd floor are "timeless" and modern functional ones are "soulless boxes". I can only chalk it to misplaced nostalgia... I'm sorry, the Neolithic called, they want their mud huts back :P
