If you are using your Google Chrome browser and suddenly notice a constant flickering after you’ve upgraded your Windows 10 computer, read on as this post will help you sort out the issue. A lot of users have reported this screen flickering issue in Chrome after having upgraded their devices to a recent Windows 10 build. The bizarre thing about this problem is that it only affects the Google Chrome browser and when it occurs, the Chrome browser will start to flash or flicker. According to users who experience the problem in Chrome, it seems to get worse when they try to play videos on YouTube or other streaming sites. To resolve this problem, many users tried to use Chrome in Incognito Mode, cleared the browser cache as well as cookies. They even tried resetting the browser settings and reinstall Chrome but nothing seems to work. Worry not though as there are still other options you can try to fix the problem and they’re easy ones so you’ll have no problem following them. The screen flickering problem in Chrome appears to be related to the Windows background and color settings as well as incompatible display drivers. This is why it is advised that you have both the video card drivers and Chrome browser updated to prevent the same problem from happening again. To get started troubleshooting the screen flickering issue in Chrome, refer to the following options.

Option 1 – Try modifying the background and colors settings

• Tap the Win + I keys to open the Settings app.
• From Settings, go to Personalization to load the Background Preferences and if this window does not appear, just select the Background option from the left side panel.
• Next, select a Solid Color as the new background from the drop-down menu.
• After that, check if the problem is fixed. This should be fixed especially if the one that’s causing screen flickering is the Windows automatic background switching.
• Once you’ve selected the Solid color as the background preference, go to the Colors tab under Personalization. This will open a new window and from there, check the box of the “Automatically pick an accent color from my background” option.
• Now close the Settings app and open Chrome again.

Option 2 – Try to update or rollback the Graphics driver

Unfortunately, there are just some cases when your hardware, GPU to be specific, might not be able to cope with the requirements, resulting in the black screen issue.

Find Out How to Get rid of Malware that is Blocking Websites or Preventing Downloads

Malware could cause all sorts of damage when they invade your computer, starting from stealing your personal information to erasing files on your PC.
