I put it wrong in words, I meant that how can I disable auto moving preview with selected annot on zoomed PDF, as in video above. I want to move annots but without moving preview.
Hello dawid.ostafin,
Currently we do not have an API to disable this so I have added it to our feature backlog. Thank you!
You could try disabling scrolling through manipulating the DOM.

Hi @tgordon !
please tell me, when will it be fixed? In current state this feature breaks the usability of our product and it is impossible to use it like this. We have a lot of complaints from our customers. It need to be solved with a hotfix or smth like that. Thanks for your help.
Hello dawid.ostafin,
This issue is actually a fix (and feature) we are planning in the next release. Thank you for your patience.

Hello dawid.ostafin,
The fix has been merged and will be available in WebViewer v8.5 which is looking to be released on May 13th. Thank you for your patience!

i mean in viewer you can see annot moves at certain area but background isn’t moving which is quite improved but still if i move annot in corners / edges in zoomed view the background starts moving which i want to disable
Hello john.ostafin,
You can disable scrolling of the page with setting a new DisplayMode then switching back to the normal display mode when not selecting/moving annotations
