Disappearing transparent geometry

In some cases when camera moves around object (transparent object) a part of this object disappear. As you can see on second image, a part of object is missing.
Is it possible to set some kind of flag to disable this geometry "culling" (the back-face culling is disabled for this object)?
When I disable transparency for this object it is rendered ok.

It's unlikely culling but maybe transparency sorting. But i'm not sure what i'm looking at here, so it's hard to tell...what is this...thing...in the center of the image? Do you have a view from another perspective?

I have figured it out, it was my fault - the missing geometry was discarded by depth test, because it was covered by other object rendered to depth buffer only.
