How to Remove the Red Border in League of Legends

If you’re a regular League of Legends player and suddenly see a glowing red border around your screen, you’re not alone — and no, it’s not an ultimate ability or some new visual update from Riot Games.

The mysterious red border bug has frustrated many players, often appearing out of nowhere and refusing to go away, even between matches. So what is it, why does it happen, and — most importantly — how do you remove it?

Let’s break it down for you.

What Is the Red Border in League of Legends?

The red border is not part of the game’s design or an enemy attack. It’s actually caused by a Windows accessibility feature known as Focus Assist’s “Ease of Access” visual notifications or sometimes by Windows Game Bar / Xbox Game Bar overlays.

In short: It’s not Riot’s fault — it’s your operating system.

The red border appears when a Windows setting is enabled that highlights active windows with a border, often used to assist users with visual impairments. However, in gaming contexts, especially with full-screen or borderless modes, this feature can misfire and create a constant, disruptive red outline.

How to Remove the Red Border (Step-by-Step Guide)

Method 1: Disable “Focus Assist” Notifications

1. Press Windows Key + I to open Settings.
2. Go to System > Focus Assist.
3. Set Focus Assist to Off.
4. Scroll down and disable any automatic rules that may turn it back on.

Method 2: Disable Game Bar Overlays

1. Open Settings again.
2. Navigate to Gaming > Xbox Game Bar.
3. Toggle “Open Xbox Game Bar using this button…” to Off.
4. Also check Captures and Game Mode sections to disable unnecessary overlays.

Method 3: Check “Ease of Access” Settings

1. In Settings, go to Accessibility (or Ease of Access).
2. Choose “Visual effects” or “Narrator” (depending on your Windows version).
3. Look for any toggles that say “Show visual feedback around the active window” or similar — and turn them Off.

Is It a Virus or Cheat Detection?

One common misconception is that the red border is related to Riot’s anti-cheat software (Riot Vanguard) or a virus. It’s not. While Vanguard may apply overlays for security purposes in other Riot titles like Valorant, and has been implemented in League of Legends as well, the red border is unrelated to its operation or any cheat detection.

Still, it’s always a good idea to scan your system if the red border appears suddenly alongside other performance issues — just in case.

TL;DR: Quick Fix Summary

• Disable Focus Assist.
• Turn off Xbox Game Bar and any overlays.
• Check Ease of Access > Visual Effects in Windows and disable visual feedback.

The red border isn’t dangerous — but it’s distracting. Thankfully, a few quick setting changes can get you back into Summoner’s Rift with a clean screen and your focus exactly where it belongs: outplaying your lane opponent.
