Additional context Add any other context about the problem here.

[di-gital]

I am having the same problem on my machine and have reproduced it from YouTube videos on Firefox 120.0 as well. This greatly slows down video decoding while greatly increasing power consumption, and happens regardless of VA-API being enabled or not within the browser. Unloading and reloading the i915kms module from the kernel resolves the issue, but is an impractical solution.
