Black stretching lines and flickering

Hello,

I have been plagued with these black lines and flickering masses shooting all over the screen and I cannot figure out what is causing it. I thought it was something to do with my monitor and I tried adjusting those settings. I even uninstalled my video drivers and reinstalled them and the same thing is happening. Does anyone know what is causing this??

Here is a link to a video that shows what’s going on: UE4 Black lines shooting everywhere - YouTube

I think it’s a material you’ve got applied to the meshes. It looks like some weird world position thing…
