Status: NEW

(Toolkit :: Picture-in-Picture, defect, P3)

Attachment: PiP video stream fails when stressing the URLbar entry point.webm

Note

• When the user plays a video (youtube/vimeo) and then stresses the URLbar entry/exit point for PiP, he will notice that two PiP windows would be opened incorrectly or the video stream might fail.

Found in

• Nightly v114.0a1

Affected versions

• Nightly v114.0a1
• Beta v113.0b7 (if the feature is enabled from config)

Tested platforms

• Affected platforms: Windows 7, Windows 10, Windows 11, Ubuntu 22
• Unaffected platforms: MacOS 11, MacOS 12

Steps to reproduce

1. Play a youtube/vimeo video.
2. Launch the PiP.
3. Click the URL bar entry point 3 times, quite fast.

Expected result

• No unexpected behaviors are observed.

Actual result

• Two PiP windows from the same source are being opened; one plays and the other is frozen. THis issue can be worked around by closing both the PiP's and opening another one.
• The video fails intermittently, causing the sound to play, but the video to turn black. This issue can be worked around if the video is paused and replayed from either the main player or the PiP OR by closing and re-opening the PiP.

Regression range

• This is not a regression considering that this feature is still in the implementation phase.

Additional notes:

• This issue might be occurring on lower-end systems or on specific ones.
• This issue is more likely to reproduce on Windows systems, but it is also reproduced in Ubuntu.
