Hi RF
Method 1:
You can try to fix this issue:
Restart your computer. This is a simple solution that often works to fix minor software issues.
Change your screen resolution. Sometimes, a mismatch between the screen resolution and the browser window can cause the white band to appear. To change your screen resolution, right-click on your desktop and select Display settings. Then, under the Resolution section, select a different resolution and click on the Apply button.
Update your graphics driver. Outdated or corrupted graphics drivers can also cause the white band to appear. To update your graphics driver, go to the website of your graphics card manufacturer and download the latest driver for your specific model.
Reset your browser settings. This will restore your browser to its default settings, which may fix the white band issue. To reset your browser settings, open your browser and go to Settings > Advanced > Reset and clean up. Then, click on the Reset settings button and confirm your choice.
Method 2:
Check Browser Settings:
Make sure that the browser's zoom level is set to 100%. Sometimes, zooming in or out can lead to display issues.
Update Graphics Drivers:
Outdated or incompatible graphics drivers can sometimes cause display issues. Visit your computer manufacturer's website or the graphics card manufacturer's website to download and install the latest drivers for your system.
Disable Hardware Acceleration:
Some browsers use hardware acceleration to render content, which can sometimes lead to display issues. Try disabling hardware acceleration in your browser settings:
For Microsoft Edge:
Open Edge.
Click on the three dots (...) to open the menu.
Choose "Settings."
Scroll down and click on "System."
Turn off the "Use hardware acceleration when available" option.
For Google Chrome:
Open Chrome.
Click on the three dots (...) to open the menu.
Choose "Settings."
Scroll down and click on "Advanced."
Under the "System" section, turn off the "Use hardware acceleration when available" option.
Check Windows Updates:
Ensure that Windows 11 is up to date. Sometimes, updates can include fixes for display-related issues.
Test in Different Browsers:
If the issue is browser-specific, try using a different browser to see if the problem persists. This can help narrow down whether the issue is related to the browser itself or something more general.
Check for Third-Party Software Conflicts:
Certain third-party software can sometimes interfere with the display. Try disabling any recently installed extensions or add-ons and see if the issue goes away.
Check Display Settings:
Verify that your display settings, such as resolution and scaling, are set correctly. In some cases, incorrect display settings can cause display anomalies.
Run Windows Troubleshooters:
Windows has built-in troubleshooters that can help identify and fix various issues. Go to "Settings" > "System" > "Troubleshoot" and run the relevant troubleshooters, such as "Display" or "Windows Store Apps."
