Post processing blendable seems to move when camera rotate

Hi, I am using a post processing blendable for a camera actor to create a security camera look. However, whenever the camera rotates, the white spots of the static noise texture seems to move, making the spots look like a snow storm. Here is a video of the “snow storm” effect. The effect looks a lot smoother in game than in the video but it should still be visible. Below shows the blendable created.


If anyone has an idea of how to fix this, please let me know! Thanks in advance!
