thanks for the report.

Can you please share the Safari version that you're using? It might be related to that.
If possible, try to update Safari to the latest available version for your OS and see if that helps

Its the lastest version. we tired multiple versions. Does not matter OS or safari version -- what matters is being or not in a mac with an intel chipset.

we've tried to reproduce this on an intel chip mac book with Safari and it didn't reproduce.

Could you please double check:

• does this also happen with vp8 or exclusively with vp9
• which exact Safari version are you using
