Strange vertical dashed line in Scene world of Unity Editor 2021.3.0f1?

Unity 2021.3.0f1
Microsoft Windows [Version 10.0.19044.1682]

Anyone knows why there is a vertical dashed line in the Scene world of Unity Editor such as below ?

I try to disable all components in the Inspector one by one but that vertical dashed line still existed in the Scene world, cannot spots any error. This will result in the “Run” and “Build and Run” display.

When I created a new empty 3D scene, there is no such vertical dashed line shown in the scene.

However, if I disabled the Skybox such as below:

The entire vertical dashed line is not shown, so I suspected is something related to the Skybox.

Anyone encounters such issues before, do share information here, much appreciated.

Please advise.

Hi Ricky,

That’s not Unity’s default skybox, isn’t it? Did you replace it? If so, check the skybox file. Maybe there is a line of transparent pixel at one edge.

hi Nina,

Thanks for the hint, it solved the problem, it is due to the custom image.

After I set back to Default-Skybox, the vertical dashed line disappeared.

Thank you.
