Can prepare a demonstration tomorrow

Expected Behavior

No Lines on tile boundaries

Actual Behavior

I could not find this issue yet, going to try to reproduce it tomorrow in a jsbin, but if someone is already working on it, let me know.

I think this was discussed to some extent here:

• MapLibre induces self-intersection in valid polygon #3156 (comment)

And also here I think:

• Simple geojson fill polygon renders incorrectly when spanning multiple tiles #4322

Please see if these are similar or not...

I think it is a new issue, since the other issues refer to older versions and I could not reproduce it there.

Version 4.7.1
https://jsbin.com/qeliceyuvo/edit?html,output

Version 5.0.0-pre6
https://jsbin.com/piwazozego/1/edit?html,output

When scrolling in and out the issue sometimes appears. I am not sure if the issue is worse on version pre.7, since I could not use in yet on jsbin. But in the reproduction the issue is less strong than in my video, where lines stay. In my video I also use a custom babylon layer. Tried to use it in the reproduction, but did not change anything yet. However, the issue is still visible.
I have to check if this only happens when using globe projection in my case. Since in the reproduction it seems like, the issue is only visible then.

What I missed to mention: Terrain is used.

This is different than the following issue, right?

• Globe: Flickering and missing layers when panning/zooming #5025

Ok I could reproduce the issue:
https://jsbin.com/zikemabepu/1/edit?html,output

To always see the issue, the terrain resolution has to be set to 512 in the jsbin. 256 seems to be the correct resolution! But the issue still appears, just not that often. So for reproduction maybe it is useful to use the 512px.

This is different than the following issue, right?

* [Globe: Flickering and missing layers when panning/zooming #5025](https://github.com/maplibre/maplibre-gl-js/issues/5025)

If I read it correctly, the other issue does not appear, when terrain is enabled. So it most probably is not related.

I see the issue, thanks!

What should we see according to your site url https://web3d.basemap.de/maplibre/dgm5-rgb/{z}/{x}/{y}.png ?
I use it with QGIS and it only produces errors with a blank screen.
