I just flew Gatwick to Paris CDG and I had 2 problems. Firstly the EFIS froze so as I taxied it didn't update bearing or the view turn with the plane but if I selected it to get the enlarged display then that enlarged display updated fine but on going back to the display in the panel it was still frozen so I could manage with the larger panel. After about a minute the EFIS started updating. Secondly I had had a message "display select panel" but no button in that panel thatcontrols what displays in the bottom display  worked during the whole flight though the standard display in that panel was updating but I couldn't display any other view. When I selected thebuttons for the alternate displays they animated but nothing changed.  Everything else has worked fine on all my flights and I don't get OOM errrors. I will fly the flight again and see if the errors are reproducible.

This sounds very similar to a problem that I have raised a ticket for when my ND, PFD and EICAS all froze in mid flight but everything else continued normally with the CDU updating correctly and the a/c continuing to fly the route properly. I was cruising on LNAV/VNAV at the time and a momentary switch to HDG SEL and back to LNAV 'unfroze' the displays. I've managed to reproduce it too.

 

It's obviously not the "long pause/freeze" that's been reported by others since that seems to relate to a total freeze of the simulation which this clearly isn't. Same as you I don't suffer from OOM's or any other FSX crashes.

 

Btw, I say I've raised a ticket but I'm not sure it registered since according to the support system I don't have any tickets currently.
