2. Toggle Hardware Graphics Acceleration in Excel
3. Disable Dropbox in Startup apps

Below, we have explained all these solutions in detail.

1] Update Microsoft Office

Check if you are running an outdated version of Microsoft Office. If so, consider updating it. Installing the latest updates is mandatory, as they fix minor bugs and add new features to the software.

2] Toggle Hardware Graphics Acceleration in Excel

Some users were able to fix the issue by disabling Hardware Graphics Acceleration in Excel, whereas for others, enabling it worked. Check if the Hardware Graphics Acceleration in Excel is enabled or disabled. Toggle the checkbox to turn it on or off and see if this fixes the problem.

Follow the instructions listed below:

1. Launch Microsoft Excel.
2. Go to “File > Options.”
3. Select the Advanced category from the left side.
4. Scroll down and locate the Display section.
5. Now, toggle the Disable hardware graphics acceleration checkbox to turn it on or off.
6. Click OK to save the changes.
7. Restart Excel.

3] Disable Dropbox in Startup apps

Some users have confirmed that Dropbox was causing the problem. To confirm this, exit the Dropbox application and then launch Excel. Now, see if flickering occurs after exiting the Dropbox. If this works, you can disable Dropbox in Startup applications so that it will not start every time you turn on your computer.

You can disable the Startup programs by using:

1. The Task Manager
2. Windows 11/10 Settings
3. Windows Management Instrumentation Command line
4. Group Policy Editor
5. Task Scheduler
6. Freeware

4] Turn off OneDrive sync for Office applications

The OneDrive sync feature for Office applications lets you work on Office files with others in real time. Sometimes, issues occur with Office applications due to sync conflicts. In that case, disabling OneDrive sync for Office Applications may resolve the issue. The following instructions will guide you on this:

1. Click on the OneDrive icon on the Taskbar.
2. Click on the gear-shaped icon and select Settings.
3. Select the Office tab and clear the checkbox that says Use Office applications to sync Office files that I open.
4. Click OK.

Now, check if the issue persists.

5] Change your default printer

Try to change the default printer and then check if this solves your problem. If you have allowed Windows to manage your default printer, you will not be able to change the default printer until you turn off the “Let Windows manage my default printer” option.

6] Troubleshoot Excel in Safe mode

There might be an Add-in causing Excel to flicker. You can check this by troubleshooting Excel in Safe mode. When you launch an Office application in Safe mode, some of the Add-ins remain disabled. This will help you find the problematic Add-in. Follow the procedure below:

• If Excel flickers in the Safe mode, one of the Add-ins enabled in the Safe mode may be the culprit. Now, go to “File > Options > Add-Ins,” select COM Add-ins and click Go. Now, start disabling the Add-ins in the Safe mode one by one and see if the problem disappears.
• If Excel does not flicker in the Safe mode, one of the Add-ins disabled in the Safe mode may be the culprit. Now, go to “File > Options > Add-Ins.” After that, select COM Add-ins in the drop-down at the bottom and click Go. Note down the Add-ins enabled in the Safe mode.

Exit the Safe mode in Excel and launch it in the normal mode. Now, go to “File > Options > Add-Ins” and select COM Add-ins in the drop-down. Click Go. Start disabling the Add-ins one by one, except those enabled in the Safe mode, because those Add-ins are not causing any problem.

Once you find the problematic Add-in, consider removing it.

8] Update your graphics card driver

One possible cause of the problem is the corrupted or outdated graphics card driver. If this is the case with you, updating the graphics card driver may stop Excel from flickering. When we say updating a driver on Windows 11/10, you can follow any of the following methods:

• Update your graphics card driver via the Windows Optional Updates feature.
