The earlier added TemplateAsset is painted slower

Hi, there. I found something weired that the add-to-stage order influents the repaint performance.

If I add templateA to panel first (since application enter), the solo displaying of A leads to a low FPS (30-);
If I have ever added templateB(or any other template), the solo displaying of A has a full FPS (60+);

Is this an issue of DynamicAtlas?

Hi! Just for clarification, you are not strictly talking about the creation performance, but the actual render performance on subsequent frame?

Are you seeing this in non-webgl builds?

I would be tempted to ask you to summit a bug report with a repro project so that we can dig deeper into this.
