Hi everyone, For a while now I've suffered this issue where, once airborne, every once in a while the FMC will freeze. The best way I can describe is as if a filter of that menu was overlayed on the FMC itself. The FMC still works, don't get me wrong, but say I press the DES page it goes there and automatically gets stuck overlayed on the FMC. If I then press PROG I will still see the DES page with thick lettering, but also the PROG page in the back. Attached you'll find an image of several pages overlayed. Any ideas?

Hey everyone, Attached is a picture of the issue. The FO side has completely unreliable altitude and airspeed indications. I had the probe and pitot heats on, and temperatures were just above 10C. As a result my A/T kept going to idle, does anyone know if this was a bug or icing? I honestly don't know what more I could've done to protect the pitot tubes? Thanks, Joep Wilmink
