:nical, since you are the author of the regressor, bug 2038650, could you take a look? Also, could you set the severity field?

Adreno 710 has similar issues as well: images, gifs and videos appear upside down and flipped horizontally.

It might be some kind of initialization thing though only reproducible on cold start. When the same site is loaded again into a tab of a running Nightly, its image/video orientations are correct.

@Walter this appears even when loading from non-fresh loading. All videos with a border radius using native video embeds have this issue, this includes tumblr, bsky, etc and happens regardless of initialization loads of the application.

I can reproduce this on a Pixel 10 Pro XL and a Pixel 6a, with the video embedded in this bugzilla comment (as viewed on the bugzilla bug-report page itself):
https://bugzilla.mozilla.org/show_bug.cgi?id=2043936#c1

Ran across this bug when tracking down a regression range (and finding bug 2038650 with this tracked as a regression).
