1922291 - WebGL's texImage2D copies old video frames since Firefox 131

Status: RESOLVED DUPLICATE of bug 1922278

(Core :: Graphics: Canvas2D, defect)

Description

[Wessel Kroos]

Attachment: Firefox - WebGL texImage2D is broken.mp4

Steps to reproduce:

I've created an isolated test case at https://codepen.io/wesselkroos/pen/MWNKZrj/f7f11e6757625699b2fdeb5adb0b7cfd

1. Go to the codepen link
2. Play the video
3. Old and current video frames are rendered to the canvas
   (See the attached screenrecording)

Actual results:

Old and current video frames are randomly rendered to the canvas.
This is a regression that started to happen today after the update to Firefox 131. Firefox 130 and lower versions are working correctly.

Oddly not all video codecs are affected. For example:

• the VP9 codec keeps rendering the first 5 or 7 frames in a random pattern
• the H264 codec (from the isolated testcase) renders old an current video frames in a random pattern
• the AV1 codec seems unaffected

This was reported by a user of my extension:
https://github.com/WesselKroos/youtube-ambilight/issues/265

All Firefox users of the Ambient light for YouTube extension are affected:
https://addons.mozilla.org/en-US/firefox/addon/ambient-light-for-youtube/

Expected results:

The current video frame should be rendered to the canvas.

The Bugbug bot thinks this bug should belong to the 'Core::Graphics: CanvasWebGL' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

A small correction to my first comment:
The AV1 codec seems to be affected as well: https://github.com/WesselKroos/youtube-ambilight/issues/265#issuecomment-2389563047

This seems dup of Bug 1922278. Fix of Bug 1922278 is waiting for review.
