Works ok in Firefox.
解决方法：
OMG @issuj you figured this out, I just tried below code and Chrome no longer crashes:
Simpy mount -v /dev/shm:/dev/shm
Or, longer, create a big shm
- Started in privileged mode:
docker run --privileged - Fix small /dev/shm size
docker exec $id sudo umount /dev/shm docker exec $id sudo mount -t tmpfs -o rw,nosuid,nodev,noexec,relatime,size=512M tmpfs /dev/shm
