1913052 - WebGL Hillshade Rendering Artifacts

Status: UNCONFIRMED

(Core :: Graphics: CanvasWebGL, defect)

Description

[felix]

Attachment: hillshading_artifacts.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:129.0) Gecko/20100101 Firefox/129.0

Steps to reproduce:

I am following a basic tutorial of the MapLibre GL JS library to display a map with hillshading. The example is available here: https://jsbin.com/qamaqifina

Everything looks fine in latest Firefox on Windows, but on Linux something is wrong.

I filed an issue with MapLibre https://github.com/maplibre/maplibre-gl-js/issues/4554 and they asked me to report it here.

Actual results:

Unexpected artifacts (grey "pyramids") appear, see attached image.

Expected results:

No artifacts appear

Comment 4

[felix]

The same artifacts appear on Windows, once I set privacy mode to "Strict", and they disappear on Linux when I set privacy mode to "Standard". So perhaps this has something to do with an anti-fingerprinting issue when rendering on Canvas outside document, but this is mere speculation on my side. Sorry for not having checked that earlier.
