Thanks for reaching out! Unfortunately, this a known Unity bug. We have reported this to Unity some months ago. The bug has been confirmed by Unity, but they have then marked it as "Won't fix" because they think this is a minor issue. https://issuetracker.unity3d.com/is...sults-in-errors-and-glitched-inspector-window As a workaround (as already suggested by you), you can disable the rendering of the material editor in the project settings under the "Easy Decal" tab. This removes the Unity UI bug, but also the in-component material inspector.
