While amateurishly digging in the console for an obvious cause on the 12th, I noticed I get this message every time I open a glitched window:
Finder: +[CATransaction synchronize] called within transaction
Which is well over my head but appears to have something to do with Core Animation:
CATransaction allows you to override default animation properties that are set for animatable properties. You can customize duration, timing function, whether changes to properties trigger animations, and provide a handler that informs you when all animations from the transaction group are completed.
Searching the console for messages related to CATransaction turns up this that occurred about a minute and a half after that day's first boot:
loginwindow[68]: CoreAnimation: warning, deleted thread with uncommitted CATransaction; set CA_DEBUG_TRANSACTIONS=1 in environment to log backtraces.
This seams to occur on login or on wake from sleep.
I also get this doozy every time the finder launches or relaunches:
