Could this be contention with other applications? Can you reproduce this issue on examples, or is it many_foxes?

looks like not application contention, I can reproduce this issue in example many_foxes after pr #10268

@re0312 did you bisect to determine that #10628 the exact cause of this?

yeah, but 10628（x) 10268(√）, I restart my computer and close unnecessary apps just now, It still happens to me after 10268,TBH,the issue is reallly weird and I checked it for several times but got the same result . It would be greatly appreciated if anyone could try to reproduce it with other computer to provide convincing proof that this is a real bug versus an environmental fluke.

I have tried running many_foxes on current main and have not been able to reproducethis. Linux intel APU laptop.

Is that a laptop? Are you always running on AC power and with GPU clock frequencies locked?

yeah,laptop with the power supply plugged in but without manually locking the GPU clock speed（default performance mod) , this issue only happens when I checkout branch after 10268 .
