Flickering in light reflections

This is rendered with E-cycles not plain Cycles btw. These are mesh lights with emission. Is there any way to get rid of the flickering effect?

The floor material has a shrinkwrapped plane with alpha on top of it. If that can have anything to do with it? I did try to change things a bit without success.

(I know about the near clip, this was the smallest video I have :slight_smile: )
