4.14.3&4.15p2 [BUG] particle cutout module renders weird on vulkan

If I add the particle cutout module like the screenshot below,the particle will render weird (flicker)with vulkan (ASTC) on my Galaxy S7edge Android 7.0.If I leave that module blank,the particle works fine.
To reproduce,just create a particle and use the main texture of the emitter material as the cutout texture,and set the Opacity Source Mode accordingly.Then package to Android(ASTC)to Galaxy S7edge.

Hey ,

I tested this with one of our assets and didn’t see any flickering. Would you mind providing the assets you tested with so that I may have a better chance at reproducing this?

Hey,

Good news! I was able to reproduce the flickering after a bit of additional testing. I plan to make a JIRA soon and will update this post when I’m done! So ignore my PM I sent earlier.
