ArgumentException: RenderTextureDesc width must be greater than zero.

[plyoung]

This error occurs when I load the project. The sprite does not appear until I click on it, click away, and click back (in hierarchy); or, I can press Play and the error will occur again but the sprite will then start showing and error stops from then on till next time i restart Unity with the project loaded. Unity 2020.2,0b2 though, so not sure if that is at fault here.

Thank you for your reporting!

[mob-sakai]

Could you please attach a minimal project (included Assets, Packages and ProjectSettings directories) that reproduces the issue?

[plyoung]

I did a few more tests and it seems to happen only if Unity is oppened while the Scene view is active (when you exited before with Scene panel active). If you open the project with Game view active then the error will not occur. My Game and Scene panels are on different tabs so not both visible (active) at same time.
