The problem is that when 2 player’s are in the server it works good but every 0.5 seconds it will update it which is causing that the Frame is glitching(visible/unvisible).
And it only needs to be updating the player’s status and not the frame itself but the text.
I see you’re using a wait function inside of the function for the for loop, if that loop has more than five parts, it will most likely run multiple times, which then will start glitching out… Maybe that’s why?
Also, in the loop you’re using x as the key, when you can just use the key variable already defined.
I don’t know what your game is about though, I so will need more context to help you more.
