Example conceals points on zoom

[jademackay]

The "Add points, polygons and text to a map" example (here) duplicated below conceals the star point when I zoom about 10 mouse clicks. It seems to be that the point is printed over when the tiles update.

using Tyler, GLMakie
using Tyler.TileProviders
using Tyler.MapTiles
using Tyler.Extents

provider = TileProviders.Esri(:WorldImagery)

# point location to add to map
lat = 34.2013;
lon = -118.1714;
pts = Point2f(MapTiles.project((lon,lat), MapTiles.wgs84, MapTiles.web_mercator))
delta = 1
extent = Extent(X = (lon - delta/2, lon + delta/2), Y = (lat-delta/2, lat+delta/2));

m = Tyler.Map(extent; provider, figure=Figure(; size=(1000, 600)))
# wait for tiles to fully load
wait(m)

objscatter = scatter!(m.axis, pts; color = :red,
    marker = '⭐', markersize = 50)
# hide ticks, grid and lables
hidedecorations!(m.axis)
# hide frames
hidespines!(m.axis)
# Plot a plygon on the map
p1 = (lon-delta/8, lat-delta/8)
p2 = (lon-delta/8, lat+delta/8)
p3 = (lon+delta/8, lat+delta/8)
p4 = (lon+delta/8, lat-delta/8)

polyg = MapTiles.project.([p1, p2, p3, p4], Ref(MapTiles.wgs84), Ref(MapTiles.web_mercator))
polyg = Point2f.(polyg)
poly!(polyg; color = :transparent, strokecolor = :black, strokewidth = 5)

# Add text
pts2 = Point2f(MapTiles.project((lon,lat-delta/6), MapTiles.wgs84, MapTiles.web_mercator))
text!(pts2, text = "Basic Example"; fontsize = 30,
    color = :darkblue, align = (:center, :center)
    )
m

#10 mouse clicks and star disappears

@nilshg reported the same thing on Slack, if you translate!(objscatter, 0, 0, 10) it "fixes" the issue for now. You could do the same to the polygon and text plots.

@asinghvi17 Oh that's a good idea, thanks! I was just looking at move_in_front! in src/tile-plotting.jl.

Maybe we should by default translate 2d maps back by 10 or so...
