Bug 1633713 - Set WS_EX_COMPOSITED to PiP window on Windows7
47 bytes, text/x-phabricator-request
Details | Review

Affected versions

  • Firefox 76.0
  • Latest Nightly 77.0a1

Affected platforms

  • Windows 7 64bit

Steps to reproduce

  1. Start Firefox
  2. Open a website with a video (Youtube video)
  3. Open the video in Picture in Picture (PiP)
  4. Resize the video to almost full screen

Expected result

  • When resizing the video to be bigger, no glitches can be seen.

Actual result

  • Glitches can be seen when resizing the video on a higher resolution.

Regression range

  • This is not a regression, it reproduces since the resize was enabled for the videos from PiP.

Additional notes

  • This is a video with the issue, was too large to upload: Link to the video
  • This is the about:support from this machine

:dholbert, could you have a look please?

Could you clarify what glitches you're describing? Is it just the video flashing black briefly while it's resizing? (That's the only thing that jumps out at me in the screencast, though maybe I'm missing something.)

In any case, this probably belongs in the Audio/Video component rather than Layout --> reclassifying.

You are correct, the issue here is that the video flashes black when resizing. I've edited the Summary to reflect that, thanks.

Mike, do you know where this should be tracked? Seems like a gfx thing, but figure you know pip best.

Flags: needinfo?(mconley)

Yes, this would likely be Graphics. If not Graphics, then video playback, but let's see what Graphics says.

Pinging Sotaro in case they have ideas. Quite interesting that it depends on the window size. Perhaps, we are hitting the time budge to process a video frame?

I am going to look into it this week.

For me, it was easier to reproduce the problem with WebRender.

(In reply to Sotaro Ikeda [:sotaro] from comment #10)

For me, it was easier to reproduce the problem with WebRender.

During resizing PiP window with WebRender, WebRenderLayerManager::FlushRendering() was called frequently than main window. It might affect to the problem on windows 7.

When WS_EX_COMPOSITED was set to PiP window on Windows 7, the problem was addressed for me.

(In reply to Sotaro Ikeda [:sotaro] from comment #15)

:bogdan_maris, can you check if the following address the problem for you?

Yep, that works for me on the machine I previously encountered this issue, I can no longer see the video flash.
