Flickering Mirror. How to fix?

I have a ship with 4 mirrors based on SceneCaptureComponent_2D
The thing is that reflection in the mirror flickering a lot plus sometimes reflection just freeze.

I have not run into that problem yet. Does the flickering always occur, or only when moving the ship? If you provided a bit more info it might be easier to help. Do you have redundant faces where the mirrors are?
