I can confirm that I also see the following side effects*:
- Lockscreen shortcut (meta + L) requires two attempts to register.
- Activities button requires two attempts to register.
- Icons in dock resize by a few pixels when you put your cursor over them.
- Additional icons no longer appear in the dock (for applications which are not already in the favourites).
* These only present themselves after I have logged out, confirmed that the dock is displaying on the lock screen and then logged back in.
