Bug 269952 – [GStreamer] Repeatedly toggling fullscreen in YouTube videos causes video to disappear

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: Media

[Caden Mitchell]

Description:

If you toggle in and out of fullscreen on a YouTube video, especially while paused, it will eventually disappear completely, and only re-appear after changing resolutions, sometimes also requiring a reload.

Steps to reproduce:

In GNOME Web/Epiphany, open YouTube.com, and click on a video. You can easily toggle fullscreen by double-clicking in the video player. Do this several times until the video completely disappears, both inside, and outside the fullscreen player.

By disappear do you mean the video placeholder becoming white?

[Caden Mitchell]

No, it becomes transparent when not maximized, and black when fullscreened (probably still transparent). Either that, or there is a sorting issue where the video is rendered behind the other content?

[Philippe Normand]

I can't reproduce this here. Sorry.

[Michael Catanzaro]

I can reproduce it pretty easily (takes 5-10 seconds of fullscreening and unfullscreening before the video disappears). This is a longstanding bug.

[Philippe Normand]

Can you provide debug logs then?

[Michael Catanzaro]

Found bug #260991, which has debug logs. This is surely caused by "Failed to get GBM buffer from swap chain: no buffers available" though

Um, I don't see transparency though. Are you seeing the "Failed to get GBM buffer from swap chain: no buffers available" error? If not, then this could be a separate issue.
