rrweb-player is not faithfully reproducing web app - showing certain elements duplicated many times

[Atrus619]

I'm trying to use rrweb to record user sessions and replay them back at a later time. Unfortunately, when replaying the application, certain elements are repeated an enormous number of times, covering the screen and making it hard to watch the video and understand what the user is doing.

Here is an image example of the issue:

Here is another example:

I can provide the events upon request (I'm currently packing them, not sure the best way you would like them provided to you).

Bit of background on my application:

1. Using nextjs / react / antdesign
2. Using the built-in rrweb.pack / unpack methods
3. I'm using scroll: 150 and input: 'last' options in sampling
4. Sending 1_000 events at a time to the backend
5. The backend is storing the packed events in mongoDB by gzipping all 1_000 events into a single document, along with relevant metadata for retrieval
6. I'm using the rrweb-player for the enhanced UI

I've tried removing the packing / sampling / gzipping, and still get the same issue, so I don't think these are related.

Is this something you have seen before / are there tricks I can do to resolve this?

I really love this library, and am really hoping I can make it work with my app!

EDIT: fwiw, I'm also seeing TONS of warnings like this when I play the recording:

[replayer] Node with id '308' not found.
{
    "source": 0,
    "texts": [],
    "attributes": [
        {
            "id": 3,
            "attributes": {
                "class": " "
            }
        },
        {
            "id": 515,
            "attributes": {
                "class": "loading-bar-container"
            }
        }
    ],
    "removes": [
        {
            "parentId": 515,
            "id": 603
        }
    ],
    "adds": []
}

as well as several errors like so:

Blocked script execution in '<URL>' because the document's frame is sandboxed and the 'allow-scripts' permission is not set.
