Feedback Random performance drop in the editor | HDRP11

This is empty HDRP 11, 2021.1b6 project and occasionally editor is loosing frames. I don't know how to pinpoint the issue.
You can see issue on Vfx graph and sliding nodes of the graph is slowed down.
This is happening randomly. Once I reopen the project, issue is gone. In my main project it is happening occasionally, this is a showcase it happens on empty project as well.

 

I actually came to post a bug thread about this, but yes I am also getting this.

It is not completely random though. If I have Firefox, Maya, or Substance open then it does this (the apps have not much going on, just having it focused once triggers this).

And editor is is fine, but as soon as I enter play mode, hell is let loose. I have to restart the editor to get rid of this.

Any idea why?
