I did a few extra things to detect the anomaly and I found that this happens mostly when running on battery (with CPU throttling).
The CPU use gets more intense the more power friendly the power scheme is. I created an issue with a linked video because this might be happening only with VirtualBox or some weird combination. https://github.com/pharo-project/pharo/issues/5417 Regards, Esteban A.
