Why does STM32CubeIDE use Chromium and peg my CPU so high on MacOS?

[Antypas.Peter]

I'm running IDE version 1.13.1 on MacOS 11.7.1 on a MBP with a dual core 2.8Ghz i7. Unlike every other IDE / CAD package that I use, STM32CubeIDE pegs my CPU really high and spins up the fans even when doing NOTHING. As in, there is no project open, no editors, no HW configuration, literally NOTHING.

Why?

I experienced similar issues with excessive CPU/GPU usage. The solution from @WojRus worked also in my case.

The CubeIDE is poorly optimized indeed.

Win 11 version 1.17 and it's till here 

ide on it"s own is not using much cpu but The  8 chromium does (2% on  16 threads 12th gen i7)

I many time kill this chromium process by hand  and it' seam not to affect any badly the ide ...

I've been noticing this a lot too, The mysterious 8 Chromium instances are (a lot of the time anyways) using more CPU than CubeIDE is!
