Steps to reproduce

Edge claims to have MJPEG support since build 10240.

I’m running Edge 25.10586.0.0 . MJPEG images do not seem to work as CSS background-image attribute. I get to see the first frame of the mjpeg, but it doesn’t update. This does work in all other browsers that support MJPEG (chrome, firefox & safari).

Reproduction:
https://github.com/sebakerckhof/edgemjpegproblem
This is a small MJPEG server which shows a webpage on port 8081 which has an MJPEG background image. Again in Edge you only see the first frame, in other browsers it updates.

    • Seems to be a rendering/painting problem.

      This fiddle contains a div with a background image referencing a public mjpeg stream served similarly to your repro: https://jsfiddle.net/dua7554t

      I am seeing the described behavior in 14393 and 14901; the video updates in other browsers but not Edge. Also, this problem is not present when referencing the stream in an img element (src attribute).

      This revision adds a hack that forces the div to repaint and the mjpeg continues to update as expected: https://jsfiddle.net/dua7554t/1/

      The reliability of the included stream is anyone’s guess, but dropping in any working mjpeg stream seems to demonstrate the same behavior.
