GStreamer debug log

Using Ephy Tech Preview with WebKitGTK 2.41.91 and GStreamer 1.22.5, play any video on YouTube and enter fullscreen mode by clicking on the fullscreen icon in the video. Then return from fullscreen and reenter fullscreen again. And again, and again. After repeating enough times (something like 5-15 times seems to be enough for me), the video will eventually break and become pure white, while the audio continues playing without issue. Because this issue is reproducible, I was able to get a GStreamer debug log, which I will attach.

Aside: this will also reproduce bug #260989, but I think that is probably unrelated because it starts happening well before the video playback eventually breaks.

Here the player blanked out right after the "Failed to get GBM buffer from swap chain: no buffers available" message flood started.

I don't think this is a GStreamer issue.

This is still trivially reproducible with WebKitGTK 2.43.4 and GStreamer 1.22.8.

Nowadays I'm guessing it's related, but I'm not sure.
