What is it on the left-top of my screen?

Dont know when it appears. Just like some kind of small nail sticky on my screen. Cannot move it, nor any menu coming up. I don’t even know what that is.

What I’m pretty sure is it belongs to Unity, because once I clicked on it, the Unity3D Editor became focused.

Could anybody know what that is and tell me how to get rid of it?

Thank you !

screenshot mate, please... put it on a public imageserver and link it.

I’m pretty sure that is being drawn by other application. Close all other processes but Unity, to see which one was drawing that icon.

I agree, that's almost certainly some crappy Windows add-on, possibly malware. Restart your computer, open a similarly full-fledged Windows windowed program like Unity and see if it appears.

https://docs.unity3d.com/ScriptReference/Graphics.Blit.html Start by reading this. Can you be specific about what needs explaining?

You mean the application icon? Does it stay even when you minimize Unity3d?
