very high CPU usage

[zephred]

Idle linux spotify-client version 1.2.31.1205.g4d59ad7c is _again_ using a lot of CPU (ofter >100%) (ubuntu 22.04)

Clearing the cache did not help.
strace fills the screen with futex, epoll_wait and getrandom but gives no clue.

It makes my machine unusable. What is spotify doing to crush my CPU ?
Is it possible to get some feedback from spotify people about that recurring problem ?

Thanks for your help.
