Bug VFX keep flickering on/off

    I can't figure out why my VFX keep flickering. The entire vfx setup turns off/on as the game camera centers over it. If the scene camera (in the editor) has all the VFX assets in view, they don't flicker. In the build, the flicker happens. I've made sure the bounding boxes are setup. Any idea what it could be? Is this a bug? I've attached a gif of the issue.
    any help much appreciated, thank you

    Do you think that you could share a small unity package with your VFX? It might be hard to help you without reproducing on my end.

    I'll try to reproduce it in a new project this week, but I figured it out, it was the 'Culling Flags'. It appears to change when you switch 'Bounds Mode' to 'automatic', but it doesn't switch back when returning bounds mode to Recorded/Manual, so its easy to end up with an unintended settings change

    thanks for the reply

    Glad to hear that you found a workaround, but it shouldn't flicker with that configuration either.
    A repro + the version you are using would be very helpful.
    Thanks!

    We're on unity 2022.3.3f1, but I was unable to reproduce in a new project. I'll submit a bug report with our full project
