Vertical lines/artifacts in Firefox

[Akodiat]

Some vertices appear to have a very incorrect height in the terrain, but this only seems to be an issue in Firefox, not Edge (I have not tried other browsers).

For example, see the example page: https://w3reality.github.io/three-geo/examples/geo-viewer/io/index.html?lat=46.5763&lng=7.9904

I am using Firefox 122.0 (64-bit) on Windows.

I had the same issue. Turns out it has got to do with spurious data in getImageData call due to fingerprinting checking. See this bug opened a month ago https://bugzilla.mozilla.org/show_bug.cgi?id=1876149 While the bug claims it is only in private browsing, it happens for all getImageData calls from mapbox because of strict tracking. Goto settings and change from strict to custom and uncheck suspected fingerprints, the problem disappears. Here is the snippet from the last comment on the bug .... Although not queryable, it is disable-able. A user can [disable Enhanced Tracking Protection](https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop#w_what-to-do-if-a-site-seems-broken) and that will disable the canvas noise. You could warn the user and provide instructions for how to handle it. Not sure why firefox is not planning to fix it

Thank you @ravirangan09! I can confirm that the issue disappears when disabling tracking protection.
