logic pro x mixer window freezes main out VU with dual monitors

In a dual display configuration, with the mixer window in the left monitor and arrange window in the right monitor, the VU meter on the last channel strip to the far right of the mixer window(which is usually the main output) freezes and does not update. This seems to be a Logic X bug, since it does not occour in Logic 9 or any other DAW with the same configuration.

Can anyone confirm this or have a suggestion for a solution?

Thanks in advance
