When 3D model showed up, it worked awesome, quick, smooth, no problems. Unfortunately, since some time it stopped working. When I click on 3D I get this black globe with izolines and wait for the map to render, nothing happens 1-2-5 minutes, still nothing.

Then I realized, I can interact with the globe and I have to click on layers to show up. So previously it was remembering the last used layer, now I have to double-click it to get it to work: 3D -> layer.

I love the 3D version! I've been thinking that Windy needs one and surprise, surprise, here it is! :D

3D works great, very smooth on Firefox, even better than 2D (where the browser feels like struggling with rendering the map).
The only con of 3D on shows country names, which is nice but is distracting and makes it harder to analyze the data beneath. I wish I could turn off/on those names.
