Code to reproduce

using GLMakie
plt = meshscatter(rand(Point3,10), color=:red, markersize=250, inspector_label=(plot, index, position) -> "foo")
DataInspector()

Code that works (note the "." after 250)

using GLMakie
plt = meshscatter(rand(Point3,10), color=:red, markersize=250., inspector_label=(plot, index, position) -> "foo")
DataInspector()
