Looks like a gfx or layout issue.

reporter, does this happen for youtube website? Or it only happened at Netflix video.

This does not happen for youtube.

I have the computer set to fall asleep based on power settings. I also have the lock screen enabled for such a case. These may send OS signals I am unaware of.

The video must have been paused before sleep. The computer must have been asleep for a sufficient period of time to cause a netflix session timeout. Netflix used to show a screen with an error code. Now it just shows the vertically shifted video. When i resume the video (for whatever tiny amount of buffer is left active) it resumes playback with the video back to its original coordinates.

JW, based on above comment, I think render should treat youtube and Netflix as same use case. But user couldn't reproduce this with youtube. Is it possible that wrong size is reported to gfx from decoder?

This is not about the size, but about the position which is decided by gfx/layout.
