Drawing with a transparency error in render view

Hi, I have a problem with a transparency eye drawing in my render view (see image below). When its blinks, a tranparency opened eye appear in the render view but in the animation view its ok. I read all support pages, cheked all transparency option in the properties and and ven search here but nothing.
I hope the community can help me!


Perhaps your render network is not fully connected.
Verify that your display toolbar is set to the display name of the display module that is connected to your render network and not “Display_All” which is a special mode that also shows unconnected modules. Use the render view to spot-check the effects at key locations.
