I attempted to do what you mentioned on the following CLI command (0 is replaced by 0-9; i.e. ran 10 times):
CPU_USED=0 && aomenc -p 1 -w 1534 -h 2000 --cpu-used=$CPU_USED -o $CPU_USED.avif example.y4m
and here are the results:
1. adding at the end of the CLI cmd only: --allintra
same bug could be observed as reported in all previous messages above (AND extreme increase in average size)
