Dots over the letters?

Several users have graphic problem with 8.51 StandardClient (without an with FP1)

After typing words every letter has a dot “over” the letter. The dot disappears after

refreshing the notes-window (moving it out of the screen).

With the BasicClient as reference, there is no such a problem.
