[Jeff Muizelaar [:jrmuizel]]

Can you capture a profile with the Renderer and RenderBackend threads enabled?

Comment 2

[Asif Youssuff]

Here is the profile: https://perfht.ml/2B73ri1 - hope it helps!

Comment 3

[Jeff Muizelaar [:jrmuizel]]

Can you "Wr" to the "Add custom threads by name" box in the profile configuration and gather a new profile?

Comment 4

[Asif Youssuff]

Sure - https://perfht.ml/2B6Zudj

Interestingly, adding "Wr" to the profiler seems to reduce the slow frame indicator animation.

Comment 5

[Asif Youssuff]

This seems largely fixed as of the latest nightly, but here is the about:support info in case it helps. Happy to consider it fixed, though.

Comment 6

[Andrew Osmond [:aosmond] (he/him)]

The profile has some animated image activity. That was probably contributing and got fixed yesterday (with more improvements in the next nightly or two).

Comment 7

[Mayank Bansal]

Quite smooth now : https://share.firefox.dev/3zXMBAJ
