PC Rainbow Lines on Screen

@AntiFox08

How are you connecting your monitor, HDMI/DVI/Display port?

A screenshot, if you can catch the issue, would be great if you could post that here.

I had to look at plays.tv after a game and pause my recent recording at the perfect moment to catch something. You can see it there on the left. That line has nothing to do with whatever texture it appears on. It just usually appears in that spot on my screen. Btw, I am using Display Port.

Posted a screenshot last Tuesday. Any advice?

No advice, but I occasionally see those lines, too. I also have a different thing going on, which is shown in the attached screenshot. The image shown is from after the end of one match and before the start of the next. I clicked on "view abilities" to look at the trooper's selected abilities, and you can see a badly-rendered copy of the final image of the previous match sort of underlying the rest of the screen. I get this sort of thing constantly behind parts of the game UI when in game.

I almost wonder if it's connected to the AMD video card, or maybe to the combination of Intel CPU and AMD video card? Or maybe even something about Sapphire cards?

My system:

i7-4770k (water cooled but not overclocked)

32 GB DDR3 (Corsair Vengeance, 10-10-10-27)

Sapphire Radeon RX-480 8GB (not overclocked, 17.11.2 driver package)

Only thing that's really unusual about my setup is that I'm running 3x 1080p monitors in Eyefinity, so my screen resolution is 5760x1080.

I see that as well sometimes. I've tried different settings, but 1080p still has it and 1080p still stutters at times. Turning off DX 12 made my performance worse rofl. Windowed and borderless are no better either.

If you only see it sometimes I'm jealous as hell. I see it all the time. Fortunately when I'm in a battle, it's only corrupting the user interface and not the stuff I have to really be looking at.

I mean, I see different UIs overlap in menus all the time, and I frequently see the rainbow streaks like in my screenshot. There's been a handful of times where lag got me killed. My connection isn't Google Fiber, but it's far from dial-up, and with my specs posted in my original post, my PC should easily be able to run this game. The fact that it defaulted to 4K and high (auto) should mean something.

I'm not hooked to a 4k monitor, but at 5760x1080, auto gives me ultra on everything and I'm certainly not bottlenecked on CPU power. In the next couple weeks I should be seeing an i7-6850k and a 1080 (not ti, unfortunately) show up, so we'll see if that fixes anything.

There's been some people with top of the line i7s and 1080TIs  struggling with lag. Not connection lag, but just general lag. If my PC meets the recommended specs yet it sometimes stutters on the main menu in 1080p (something Battlefront would still do if I reinstalled it), it's gotta be something with the developer.
