Created attachment 443537 [details] kernel panic webkit Running safari in a situation that occupies a lot of CPU/GPU such as WindowServer and xcode build causes frequent kernel panic. I have found that kernel panic does not appear in other browsers that can disable GPU hardware acceleration, but since Catalina, Safari no longer provides GPU hardware acceleration disable. I attached logs of kernel panic below. Thanks

An issue that resulted in such kernel panics was fixed in an underlying macOS component in macOS Monterey (cf. rdar://80727239 for Apple employees). If this continues to reproduce, please file a report at <https://feedbackassistant.apple.com>. It would be very valuable to include a kernel core dump in the report.
