Hello all,
When using globe projection and very high angles of pitch, I am seeing a gap between the horizon and the sky during the zoom 11 to 12 transition.
Looking for existing issues, I see the discussion in #4853 during the development of globe mode, where it is known that there's no easy solution for handling sky when zoomed out and the decision was made to limit sky to zoom 12 and beyond. #4878 (comment)
At zoom 12 and beyond, the sky-color and the horizon-color correctly render on top of the land, fading across the land/sky boundary and correctly filling the gap. But between z11 and z12, the sky-color and horizon-color stop higher up on the screen, causing a gap.
You can just barely see the gap in the live demo here, if you enable globe and tilt the map to maximum pitch and zoom out until you are between z11 and z12:
Tiny white gap visible here:
It also might be sensitive to the aspect ratio of the map div itself. If you have a very tall and narrow map, the gap seems much more visible.
Here's a screenshot of the problem in the map I'm working on, in two very vertical frames, the one on the left with 3D terrain enabled (which almost but not quite covers the gap) and the one on the right without terrain, which shows the gap very prominently. I've got a black page background here so the gap is black. This is at zoom 11.15, with a pitch of 85.
And here's a jsbin, using a copy of the Sky, Fog, Terrain demo, with adjustments to the zoom (11.25) and view angle (pitch of 85) and adding the globe projection so you can see the white gap: https://jsbin.com/pamohav/edit?html,output
If I change the zoom in that demo to 12, you can see what I'm talking about that the horizon-color correctly fades down across the "horizon", which it does not do at zoom 11.25
