Roblox white on black outline specs

Hello there for the past months I have been making a roblox catalog game but I can’t seem to understand why sometimes white specs/ dark ones appear when for example viewport goes with the image label background

That’s just a problem with how Viewport frames work, it is widely talked about in the forum, and the best “solution” is to set the background to a similar color, like these guys explain in another post

I personally dislike Viewports because of this and always try to take a different approach.
Here you could instead make it so it changes the character appearence in game, dettach and set the camera in front of the player, and make the player stuck in place by setting their walkspeed to 0.
