This appears to be a paid plugin called Royal Slider, similar behavior is reproducible on https://dimsemenov.com/plugins/royal-slider/gallery/

Hi Hiroyuki, would you be able to take a look at this?

This is probably a duplicate of https://bugzilla.mozilla.org/show_bug.cgi?id=1679649

Comment 4

[Hiroyuki Ikezoe (:hiro)]

No, that one is caused by a different problem. I am still investigating this, haven't found where the underlying problem is, but anyway, this case is caused by overflow: visible transform offset from the reference frame, and the overflowed area is offset-ed side.

The severity field is not set for this bug.
:hiro, could you have a look please?

For more information, please visit auto_nag documentation.

The gallery from the reported site is now gone, an the second linked webcompat issue is not reproducible anymore.
I came across one more report with adobe.com that seems to be related to this issue. Setting layout.animation.prerender.partial to false makes animation work.

Comment 7

[Dennis Schubert [:denschub]]

:hiro, given this appears to now affect adobe.com, can you take a second look at this and see if the priority should be raised? This is still Nightly-only, but it would be good to have a look anyway.

[Hiroyuki Ikezoe (:hiro)]

I am going to disable the feature, partial pre-render, on all channels in bug 1760918.

[James Graham [:jgraham]]

Since this got disabled, I think we can unset the Webcompat Priority flag
