I am thinking this change.
https://chromium-review.googlesource.com/c/chromium/src/+/1258787
It was landed on 11192.0.0.
We should check Chrome OS 11191.0.0 and 11192.0.0. Or deploy chrome before the change.
I'm confirming whether the CL in #6 is the root cause.
Aka, please feel free to take over if that CL is indeed the cause.

Quick update:

I also encountered this issue at H264, and it still existed after reverting the CL.
Status: Assigned (was: Untriaged)
The issue started to occurred between 11176.0.0 to 11177.0.0.
Especially 11177.0.0 I even saw the black screen flashing at OOBE.
I will bisect the chromium CL next.
Issue is currently marked as RBD. Next Dev is targeted for Thurs 11/8. Will need fix before then.

The bisect result is this CL:

Hi Kristian, can you take a look at this?
The CL is already being reverted.
Can someone provide an update here? Did reverting the CL fix the issue?
The CL has been reverted and the revert has been confirmed to fix the other issues.

avkodipelli@ can you please confirm the fix and close this issue if so?
