Does anyone know if the MaterialTheme or Ripple effects can be disabled. They seem to be quite laggy on the current versions and I was wondering if they can simply be turned off to improve performance?

[romainguy]

If there are performance issues it would be best to fix it instead of disabling the feature. On what version of compose and which device(s) do you observe this issue?

[Adam Powell]

I'll venture a guess that this is more about the ripple effect stalling behind large recompositions in a frame since it's animating on the main thread along with those recompositions at the moment

[Madhava]

Iv been using multiple versions since dev09, latest is dev14, my device is an LG G6 on Android 8

[Madhava]

The emulator is similar. I notice when I tap on any element the ripple is really slow

[romainguy]

Slow or skipping frames?

[Madhava]

My next step was to do some frame debugging, whats the best way to do that in the latest canary's?

I cant seem to get it to say skipped frames anymore if i just keep tapping the checkboxes or buttons

[Madhava]

so i guess its going to 50% CPU after i tap

[Madhava]

does that mean the render threads are taking 600ms to complete?
