Masked material on huge particles black flickering
I've been doing some FX work lately and for test's sake decided to switch to masked material to test things out and i've noticed strange black flickering on it. I've isolated the issue as far as i could and this is what i've come up with.
This is how the flickering looks like: https://gyazo.com/96150e8b224a85a0f5df1bf64a86356f
And this is the material, its pretty simple. It also flickers for a default lit masked material:
This is how the particle system looks like (you can even see the flickering in there):
To reproduce this effect i just have to:
The effect is the most visible when the Screen Alignment is changed to PSA Velocity, though it also flickers in other screen alignment modes. I reproduced it many times on 4.18.3 in few projects, though on 4.17 it doesn't seem to happen. It is also worth pointing out that i am running on Radeon RX480 and AMD FX-8350, since one of my peers couldnt reproduce the issue on his Titan card and Intel cpu.
Can anyone except me reproduce this issue? Or maybe someone has an idea on how to fix it, since my eyes hurt from constant flickering. Hope it will just go away in 4.19.

It seems like it is not a bug, but a typical z-fighting issue. If you are set on using masked particles, give them more spacing between each other.
