<p dir="auto">I can reproduce this on the openmaptiles demo page ( <a href="https://www.maptiler.com/maps/#style=openstreetmap&lang=auto&mode=2d&position=12.75/51.31018/-0.68644" rel="nofollow">https://www.maptiler.com/maps/#style=openstreetmap&lang=auto&mode=2d&position=12.75/51.31018/-0.68644</a> ) and also with other unrelated maplibre styles (e.g. Thunderforest Atlas). So I'm confident that it's an upstream bug.</p>
<p dir="auto">Going by the pattern of behaviour (the vertical striping appearing on polygons with a pattern) then I suspect it will have a similar root cause, somewhere in WebGL texture handling. It might be worth adding additional information about this specific behaviour to the maplibre tracker, either in the same issue or in a separate one.</p>
<p dir="auto">Since this is not something we can fix here, I'm going to close this issue. Thanks for the report <a class="user-mention notranslate" data-hovercard-type="user" data-hovercard-url="/users/oblyn/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/oblyn">@oblyn</a></p>
