2D Renderer, SceneView camera not cleared by color result, leaves render traces.

I’m using URP 2D Renderer(Experimental)

Game camera BackgroundType is set to solid color, so there is no problem, but in sceneView, it leaves traces like they dont clear color buffer.

If I change camera BackgroundType to SkyBox, then game view shows same result too.

Does someone know what is causing this?

Above problem was occuring in 2020.1.16f1, now I’m using 2021.1.15f1 URP 11 problem disappeared. Solved.

I have same problem, however I can’t upgrade unity version.
The solution is remove skybox material in environment tab.
