Mobile-Only Visual Bug

Help and Feedback Scripting Support

Can see the video in the link. There’s a black dot in the bottom right of the video. When over a BasePart, it appears, when not over a BasePart it disappears.

This only appears in Mobile. Does not appear in Studio. Does not appear when using the Device Emulator.

I’ve run prints via

for _, descendant in game:GetDescendants() do
  if descendant:IsA("BillboardGui") or descendant:IsA("Highlight") then
    print(descendant.Enabled, descendant:GetFullName())
  end
end

I can’t find anything enabled that might be causing this - and it only happens on Mobile, never happens on PC.

I can even go so far as to clear the entire workspace hierarchy except for a Part and a MeshPart and still see the random black dot. While running a print workspace:GetDescendants() that confirms these are the only things in workspace.

So wait, your saying that when you delete the part and meshpart, the dot disappears?

Also, are your quality settings different on mobile compared to on pc? It could be something with the quality settings difference which can effect how stuff is rendered.

Like in the video, if the camera view where the dot ‘should be’ is over open space, the dot doesn’t appear, if there’s a part where it ‘should be’ it appears.

I’ve tried deleting these specific parts and leaving other parts and it will appear on the other parts as well.

I just ran a test and it will appear on anything Graphics Level 4+ on mobile. Still doesn’t appear in studio no matter what. Also doesn’t appear at any graphics level when playing on Windows.

Just ran a test - if I change the game.Lighting.ClockTime, I can make the black dot move without moving the Camera.

That probably means it’s something to do with lighting.

First, try putting the reflectance on your parts to 0, maybe that could fix it.

If that doesn’t work, try messing with the properties in Lighting Service, maybe there is a property that is causing that.

I’ll look through the docs for lighting service and see if there is anything that may be cause the dot.

I’m going to fill out a bug report.

I couldn’t find any specific properties that could be causing it, but all of them seem to possibly have some sort of impact on the dot.

I would just try to mess around with all of the properties of lighting service and see what happens, also, this could be a bug too, so making a bug report would be a good idea.

If you are going to mess around with the lighting service properties, you should probably make a backup for your place, just in case you change something and don’t know how to reverse it.

I hope I was able to help you in some way!
