Objects disappear

[zandro]

Hi,I have a problem that occurs primarily on mobile devices (both on ipod touch, Android, playbook). Sometimes an object in the scene suddenly disappears for a few seconds and then reappears. The object disappeared continues to move and interact normally just is not rendered. The material does not have any special settings, is like other and even if occurs mainly with the object of the player sometimes it happens to other objects. Perhaps it is a problem of video memory? Or some bug?

i had a similar problem some days before in my game,
i use a glass surface over other objects.
changing the material priority lower to 0 the other objects don't disappear sometimes.
the option use painted vertex alpha was in relation.
