Guis in StarterGui with ResetOnSpawn do not get garbage collected

[RVVZ (Emperor)]

Having a GUI with ResetOnSpawn enabled placed in StarterGui will cause memory under “Gui” to keep raising each time the character is respawned and will not lower.

Here is a quick alternative to getting around this that I did: I put the GUI in a folder in ReplicatedStorage, and cloned it into PlayerGui with a local script on each Player.CharacterAdded (place in StarterPlayerScripts).

Code

local plr = game.Players.LocalPlayer

    plr.CharacterAdded:Connect(function()
    	for _,v in pairs(game.ReplicatedStorage.Folder:GetChildren()) do
    		v:Clone().Parent = plr.PlayerGui
    	end
    end)

This was the result I got, which shows that the original problem is most definitely caused by StarterGui and how it handles the ResetOnSpawn:

Massive PlayerGui Memory Leak on Server When Players Leave Game

If your game’s scripts currently hold references to the PlayerGui after the Player leaves. You will still be able to access them though the reference you hold from before the player left. However, after the player leaves the game (when the Player is removed from game.Players), the PlayerGui’s parent …

@PeZsmistic thanks for referencing this! It’s possible that this issue may be slightly different since this leak appears to happen on respawn (as opposed to the leak you posted, which appears to occur when the player leaves the game).

@RVVZ thank you for the report! I’ve assigned a ticket to investigate.
