Way to query usage of desynchronized canvas for canvas2d and WebGL?

[Colin Blundell]

Hi Blink folks,

I'm interested in querying the frequency of usage of desynchronized canvas with canvas2d and WebGL (relative to the overall frequency of canvas usage). For the latter, I'd ideally like to also break it down by the value of `preserveDrawingBuffer` as well.

Before I go in and add custom UMA, I was wondering: Is there already a way to formulate this query via known tooling?

Thanks,

Colin

There are blink UseCounter for low-latency canvas, but I don't think we have anything for preserveDrawingBuffer.
