Try this in order:
- Reset the graphics driver once. Press Windows logo key + Ctrl + Shift + B. If the blinking stops, the issue was likely temporary graphics driver instability.
- Check whether Task Manager also flickers.
- Press Ctrl + Alt + Delete and open Task Manager.
- If needed, press Ctrl + Shift + Esc.
- If Task Manager flickers too, the problem is likely the display driver.
- If Task Manager does not flicker while the desktop does, the problem is more likely an incompatible app.
- If Task Manager flickers, fix the display driver.
If Windows Update recently installed updates, try a rollback first:
- In the taskbar search box, type Device Manager and open it.
- Expand Display adapters.
- Right-click the display adapter > Properties.
- Open the Driver tab > Roll Back Driver > Yes.
- Restart the PC.
- In Device Manager > Display adapters.
- Right-click the adapter > Update driver.
- In Device Manager > Display adapters.
- Right-click the adapter > Properties > Driver tab.
- Select Uninstall Device.
- Select the checkbox to remove/delete the driver software if shown.
- Restart the PC so Windows attempts to reinstall the driver.
- If Task Manager does not flicker, check for an incompatible app.
Update apps first:
- If the app came from Microsoft Store, check for updates in Microsoft Store.
- If it did not come from Microsoft Store, get the latest version from the app manufacturer.
- Go to Start > Settings > Apps > Installed apps.
- Select the app > Uninstall > Uninstall.
- Restart after each removal and test whether the blinking stops.
- If the screen is too unstable to follow the steps, start in safe mode first and then perform the driver or app steps.
A Microsoft Q&A case for blinking desktop icons also suggests trying a clean boot to identify whether a background service or startup program is causing the refresh behavior.
