Gantt software started lagging while using Apple M1

So, did you send kill -3 exactly at the moment when CPU usage was high?

I’m not sure so I’ve reproduced the kill -3 message using both Java 11 & 17 when CPU usage goes over 100% in Activity Monitor. Find files attached below.

Hey @DmitryBarashev - any luck with this? Is there anything else I can try/provide to help?
