Studio UI Rendering / CoreGui Issue

At random moments the leaderboard/PlayerList interface changes to a legacy/classic style. The UI appears as a plain text list without proper info resembling the old roblox. The previous play session had a normal, modern PlayerList UI. This has now happened twice. The first time, I fixed it by completely restarting Roblox Studio. However, I cannot be certain whether this issue will occur in the live game for actual players.

Additionally, when I press Tab, a strange menu opens in the center of the screen showing players and leaderstats, which is NOT the standard PlayerList interface. I also confirmed that this is NOT the player interface in PlayerGui.

What I have checked:

  • I do not have any scripts that modify the standard PlayerList interface.
  • There are no backdoors or viruses in my game.
  • I performed a full project search for “game.StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.PlayerList, false)”. found nothing.
  • I also checked every require() call in my game to ensure no external module is interfering.

Actual behavior: The PlayerList occasionally reverts to a legacy/classic style, requiring a full Roblox Studio restart to temporary resolve

UPDATE: I fixed it by setting “Device Emulation” to HD 1080. It might have been the Xbox One interface.
