We have to update a lot of small onscreen objects and performance is way
better, when we travers them outside the Cocoa view tree. If we would use
invalidating, we would have to go thru our complete view tree and check for
overlaps with the update rect.

That's not the point. The point is a program has to be ready to handle the
possibility of corrupted, truncated or fragmented data.
Writing a client-server program, particularly at the socket level, is not easy
for that very reason. If you fail to take the possibilities into account, you
If you set it to a color that isn't black, you will be able to see a
difference. Black behaves this way because selection is shown by making the

That has nothing to do with the issue of UTF-8 sequences being split across
