Weird light trail in build

Hello,

Newbie here. I create a sample level. I just wanted to test and build the game but I am getting this weird light trails which I don’t see in my unity window during building. It seems to only effect the background of the camera.

I haven’t set any graphic background yet (which probably will fix this) but just wanted to know if this is normal or anyway to fix it without putting a background?

Using the new pipeline that have 2d lights.

Hi all, just wanted to update. I went into camera and changed the environment/Background Type from SkyBox to Solid color and that seems to fix it. Maybe this issue was due I had SkyBox setting but I never set that to anything? Anyways, this is how I resolve it. Hope this can help some ppl out. Sorry, I haven’t touch the SkyBox option before so I donno if that if it is a bug or not. Maybe later I will try to create a skybox?

haha yeah
