flash video freezes the whole system

[yogi81]

Hello. I am using linux arch with latest intel drivers. (latest va + latest released vdpau-va-gl)

The following video freezes the whole system:

https://rutube.ru/video/51d83cc285352e35463dcb7f7b343dc4/

I am not able to collect any logs, because of a hard system lock up.

When system freezes the sound continues to play.

Do you need more information to reproduce the issue?
