Arc Browser has quickly gained popularity for its sleek design and productivity-focused interface. However, some Windows users notice visible borders or window edges when using full screen mode, which can disrupt the immersive experience Arc is known for. These borders may appear as thin lines, taskbar remnants, or window frames that refuse to disappear.
TLDR: If borders are visible in Arc Browser full screen on Windows, the issue is usually caused by Windows display settings, taskbar behavior, graphics scaling, or Arc configuration quirks. Simple fixes such as enabling true full screen mode, adjusting taskbar auto-hide, modifying display scaling, or updating graphics drivers often resolve the problem. Advanced fixes include tweaking Windows visual settings or using compatibility options. The five solutions below are easy to follow and work for most users.

Why Borders Appear in Arc Browser Full Screen
Before applying fixes, it helps to understand why borders appear in the first place. In most cases, the problem is not a defect in Arc Browser itself. Instead, it results from:
- Improper full screen activation (maximized is not the same as full screen)
- Windows taskbar overlay behavior
- Display scaling mismatches
- Graphics driver rendering glitches
- Windows windowed mode optimizations
Identifying the root cause makes it easier to apply the correct fix.
Fix #1: Use True Full Screen Mode (F11)
One of the most common mistakes is confusing a maximized window with full screen mode. Clicking the maximize button simply enlarges the window but does not remove all window borders.
To activate true full screen mode in Arc Browser:
- Open Arc Browser.
- Press F11 on your keyboard.
- Wait for the interface to hide borders completely.
This shortcut forces Windows to remove window chrome and enter immersive mode. If borders were caused by standard maximization, this will resolve it immediately.
Tip: Some keyboards require pressing Fn + F11.
If the border persists even after pressing F11, move on to the next fix.
Fix #2: Enable Taskbar Auto-Hide
Sometimes, the “border” is actually a subtle taskbar edge. Windows may reserve a few pixels at the bottom or side of the screen, creating the illusion of a border.
To enable auto-hide for the taskbar:
- Right-click the Windows taskbar.
- Select Taskbar settings.
- Toggle on Automatically hide the taskbar.
This forces Windows to remove the taskbar unless actively accessed.
Users with multiple monitors should also check taskbar settings for secondary displays, as borders sometimes appear only on extended screens.
Why this works:
Windows sometimes keeps taskbar priority over applications, preventing true full screen immersion. Enabling auto-hide minimizes interference.
Fix #3: Adjust Display Scaling Settings
Improper display scaling can cause thin white or black borders around applications. This is especially common on high-DPI displays configured with 125% or 150% scaling.
To adjust display scaling:
- Right-click the desktop.
- Select Display settings.
- Scroll to Scale and layout.
- Set scaling to 100% temporarily.
After adjusting scaling, restart Arc Browser and test full screen mode again.
If 100% scaling fixes the issue but makes text too small, try logging out and back in after applying your preferred scaling value. This forces Windows to recalculate application boundaries.
Advanced option: Right-click Arc’s shortcut → Properties → Compatibility → Change high DPI settings → Enable “Override high DPI scaling behavior.”
Fix #4: Disable Windows Windowed Optimizations
Windows 10 and 11 include full screen optimizations designed for games. Occasionally, these optimizations conflict with modern applications like Arc Browser.
To disable windowed optimizations:
- Right-click the Arc shortcut.
- Select Properties.
- Go to the Compatibility tab.
- Check Disable full screen optimizations.
- Click Apply and OK.
This prevents Windows from applying performance overlays that may cause visual borders or edge artifacts.
When this fix works best:
- Persistent thin borders remain despite F11.
- Border flickers during video playback.
- Multiple monitor setups show inconsistent behavior.
Fix #5: Update Graphics Drivers
Outdated GPU drivers can cause rendering problems, including partial borders in full screen mode.
To update graphics drivers:
- Press Windows + X.
- Select Device Manager.
- Expand Display adapters.
- Right-click your GPU.
- Select Update driver.
For best results, download the latest drivers directly from your graphics card manufacturer (NVIDIA, AMD, or Intel).
After installation, restart your system and test Arc full screen again.
Why this works:
Full screen rendering relies heavily on GPU optimization. If Arc and Windows disagree on boundary mapping, borders may appear due to driver miscommunication.
Quick Comparison of All Fixes
| Fix | Difficulty | Best For | Success Rate |
|---|---|---|---|
| Use F11 Full Screen | Very Easy | Maximized window mistaken for full screen | High |
| Taskbar Auto-Hide | Easy | Bottom or side screen borders | High |
| Adjust Display Scaling | Moderate | High DPI screens | Medium to High |
| Disable Full Screen Optimizations | Moderate | Persistent thin borders | Medium |
| Update Graphics Drivers | Moderate | Rendering glitches | High |
Bonus Tips for a Truly Borderless Experience
If borders still persist, consider these additional adjustments:
- Ensure Windows is fully updated.
- Restart Windows Explorer via Task Manager.
- Try switching Arc to another monitor.
- Disable third-party window management software.
- Test in a new Windows user profile.
In rare cases, Arc may require a reinstall if configuration files are corrupted.
Frequently Asked Questions (FAQ)
1. Why does Arc full screen still show a thin white line?
This is usually caused by Windows display scaling or GPU driver rendering issues. Adjust scaling to 100% temporarily and update your graphics driver to resolve it.
2. Is maximizing the window the same as full screen?
No. Maximizing enlarges the window but keeps borders and window framing active. Pressing F11 activates true immersive full screen mode.
3. Does this issue happen only on Windows?
It is more common on Windows due to scaling and taskbar behavior. macOS handles full screen differently, which reduces border issues.
4. Will disabling full screen optimizations affect performance?
For browsers like Arc, performance impact is minimal. This setting mainly affects gaming optimization.
5. Can multiple monitors cause borders in Arc?
Yes. Mixed resolution and scaling setups can create boundary calculation conflicts. Ensure consistent scaling across monitors.
6. Should I reinstall Arc Browser?
Reinstalling should be a last resort. Most border issues are caused by Windows settings rather than the browser itself.
Final Thoughts
Removing borders in Arc Browser full screen on Windows is usually simple once the underlying cause is understood. In most cases, enabling true full screen mode or adjusting taskbar settings immediately restores the immersive experience. For more persistent issues, tweaking scaling settings, disabling Windows optimizations, or updating graphics drivers typically resolves the problem.
With these five easy fixes, users can enjoy Arc Browser the way it was meant to be experienced: clean, distraction-free, and completely borderless.
