Somehow, some defaults setting or something in Lion on my MacBook Pro has gotten set terribly wrong, because starting recently, my inactive windows (and certain other window chrome) have gained what I presume to be 10.4 Tiger-style pinstripes.
Behold the horror:


Obviously, this is not acceptable in any way. I don't know what I did that made these appear. I've looked through Secrets, but haven't found anything relevant. Does anyone have any ideas?
EDIT: I just realized that in addition to the pinstripes, windows' corner radii have grown larger, as they were in Tiger and before, as well. What in the world is going on?
