[blink-dev] Re: Compositing Reasons

2022-11-14 Thread 'Pea Wyllie' via blink-dev
I did do that for testing and how I knew to use the Compositing Reasons; 
but for my use case I need these layers to be specifically identifiable, so 
I was using the attribute.

[blink-dev] Compositing Reasons

2022-11-14 Thread 'Pea Wyllie' via blink-dev
Hello, I've got a use case in which I need to get certain DOM elements into 
their own layer. I've added a new HTML attribute for this purpose, and 
added a new Compositing Reason to the layers that have this attribute. 
However, when I go to a test site on my Chromium build running with 
--show-composited-layer-borders, I do not see my elements in their own 
compositing layer. Is there an allowlist elsewhere that is necessary to 
pick up those changes? Or is compositing reasons just for metrics or 
something and the actual logic resides elsewhere? Thanks!
