Hello,
Thank you for posting in Microsoft Q&A.
Based on the description, I understand your question is related to Flickering Desktop of Laptop.
Screen flickering in Windows is usually caused by a display driver issue or incompatible app. To determine whether a display driver or app is causing the problem, check to see if Task Manager flickers. Then, based on that information, you'll need to update, rollback, or uninstall your display driver or update or uninstall the app.
Press Windows logo Key + Ctrl + Shift + B may fix your issue. If this does not work, see if restarting helps.
Press Ctrl + Alt + Delete to open Task Manager. If you don’t see Task Manager after pressing Ctrl + Alt + Delete, press Ctrl + Shift + Esc to open Task Manager.
If Task Manager flickers along with everything else on the screen, a display driver is probably causing the problem. In this scenario, see the Fix your display driver section.
If Task Manager doesn't flicker while the rest of the screen is flickering, an incompatible app is probably causing the problem. In this scenario, see the Update or uninstall an incompatible app section.
If Windows Update recently made updates to your device, roll back your display driver. Otherwise, try updating or uninstalling your display driver to fix the flickering or scrambling problem.
In the search box on the taskbar, type device manager, and then select it from the list of results.
Select the arrow to expand Display adapters.
Under Display adapters, right-click the adapter, then select Properties.
Select the Driver tab, and then select Roll Back Driver > Yes.
Restart your device.
Have a nice day.
Best Regards,
Molly
