Texture quality issue

I’ve noticed a problem with my textures on my game and I’m not sure what’s causing it. When I’m playing the game they flicker slightly.

I’ve attached a screenshot, it’s the texture of the road/barrier directly in front.

Any ideas how I can fix it please?

the only time I have noticed any flickering, it had to do with the camera. Meaning, either the camera was moving in, past the images, or, the zoom in and out, was caught in a bad loop, zooming in and out very quickly, causing a flicker of sprites.

No, it’s not that.

Here’s a video of it, Can only really be seen in HD though.
