Have any one else experienced a massive javascript hit (6-7 seconds), when showing line chart visualization in the latest Kibana ?

I'm pretty sure its some sort of of javascript bug.

If I make the same visualization using TSVB, it works just fine, with the same indices and filters.

Yes, we are aware. One of my teammates merged a fix earlier today, which will be released in 7.9.1 [https://github.com/elastic/kibana/pull/75850](https://github.com/elastic/kibana/pull/75850)
