The reason we're missing the update, and why the pixmap hack works, is because the borders are drawn directly on the _screen_ pixmap. That explains why the coordinates still make sense, even though we're hooking a pixmap instead of a window. Not sure what the fix is. Starting to activate hooks even for just the screen pixmap still means we have to audit the code for assumptions about windows. Not terribly appealing. I'll dig around and see if I can find something cleaner...
