Black flickering on clothing simulation

So I started playing around with the cloth tool in UE4 trying to simulate the lower part of the coat of my character realistically but some black flickering on the simulated cloth have appeared and I don’t know what is causing that.

Here is a gif showing what exactly I am talking about:

and also a video if it helps:

your gif doesnt show and if your going to post a video do it to a site like youtube (we dont want the potential for viruses and such)

alright ok

Got tired of waiting for a reply and looked for a solution by trial and error.
Turned out to be a problem with the UV, unwrapped again and the glitches disappeared.
