Team's UI Performance are Abysmal for a Major Product

Hi Teams, 

I would like to report that the UI performance of the Teams SPA are unacceptable in my opinion for a product of its size and scale. 

On my very decently equipped work computer (recent i7 quad core + 16GB ram + SSD), simply switching between conversation puts the whole machine to a sluggish state, in the trace below, you can see that switching from one conversation to another takes a whooping >2000ms to complete

Not a single frame during that time was above 5 fps

All of my coworkers at my org are struggling with Teams' performance issues, audio is cutting out frequently when they open another program... it's just everywhere and people are getting used to it I guess.

I see so many levels in the render call stack, angularjs, mixed with jquery mixed with some React? What is the state of UI performance? Is there a new version coming up? and what is being done to address this major issue?

See the attached trace for reference.

Thanks,

Philippe
