My GPU particles (cascade) are disappearing/flickering when moving camera

How to fix? I have auras with big particle effects and whenever moving or running the particles flicker all the time. When standing still without moving camera they mostly always work perfectly, but when I’m looking on certain angles the particle effect has completely disappeared until I move (and always doesn’t render on that angle). Did some searching, but couldn’t found a working fix to this problem.

Hope somebody can help.
