GPU particle disappear

Used water_fall gpu particle from particle demo. got sad problem - it dissapeare when camera moves. After camera stops - it appear again

Hello Stunder,

I just added the P_WaterFall gpu particle system from the Particle Effects content folder to a clean blank project in 4.9. I then moved around the particle in both the Editor Viewport and in Play mode. Everywhere I move I see the particles. I did not change any parameters or textures within the project or the particle itself.

If you would provide reproduction steps for how you migrated this asset to your project, a screenshot where you are not seeing this particle showing in your viewport, and a copy of your DxDiag.

After I have this information I should be able to determine what is causing this particle system to disappear.
