from RootLayer.
  That's because, I guess, I need to lock something before setting the mode. Am 
I right ?
  I couldn't find any hint in the code.

        All commands that affect the visible regions must be executed from 
RootLayer's
thread context. When rebuilding regions, again, that must be done from 
RootLayer's thread
context. The solution: redirect this message to RT thread and add a handler for 
it.
        Locking RootLayer is not a solution, that must be kept to a minimum (2 
such
situations ATM).
        (see GoInvalidate() as an example)
