Skipping/seeking videos on Twitter creates blocky artifacts. Attached is an image side by side of the video open in Firefox and in Chrome after being skipped to the same timestamp. Issue also does not occur on Microsoft Edge. All browsers have Hardware Acceleration enabled. Is there a fix?

Do you have resistFingerprinting enabled as that can cause such effects?

Does it still happen in Troubleshoot Mode?

Yes, the problem persists in troubleshoot mode.

So that rules out hardware acceleration and extensions.

Does it still happen in a new profile? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile.

Installed Developer Edition and problem persists.

If you have any codec packs installed, try uninstalling or updating them.

If you save the video and play it in Windows Media Player, do you see the same thing there?

No issues in media player. I don't believe I have anything in particular installed related to codecs as this is a fresh install of Win11 from around a week ago.
