Stripped nCount distribution for custom bin 10 um in Visium HD

[npont]

Hey all,

When running
SpatialFeaturePlot(object, features = "nCount_Spatial.010um", pt.size.factor = 1, image.alpha = 0.5)

I get a stripped distribution of the nCount on my tissue (processed with spaceranger and Seurat) as you can see in the screenshot. This happens for the custom bin 10 um but not for the binnings generated by default by spaceranger (2 um, 8um, 16um).

Of course when playing with the pt.size.factor I am able to make those odd kind of dots disappear but I think that's concerning.

Anyone already encountered such an issue or has any clue about the source of the problem?

Thanks!
