Screen flickering in Windows 11: distinguish a display driver from an app

Use the Task Manager flicker test and graphics-driver reset before changing the wrong part of Windows.

Applies to: Windows 11Change risk: Low to mediumReviewed: 2026-09-17
Do this first
  1. Press Windows + Ctrl + Shift + B once to reset the graphics driver.
  2. Restart Windows if the flicker continues.
  3. Open Task Manager and observe whether it flickers at the same time as the rest of the display.
  4. Note whether the issue began after a display driver or app update.

What this problem usually means

Microsoft’s current troubleshooting path separates display-driver problems from incompatible apps by observing whether Task Manager flickers with the rest of the screen. That diagnostic branch is more useful than immediately reinstalling every display component.

Ordered repair path

Work from the narrowest fix to the broader one.

1

Use the Task Manager flicker test

Low risk

Why this belongs here: Microsoft uses this behavior to separate a likely display-driver branch from an incompatible-app branch.

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Watch Task Manager while the flicker occurs.
  3. If Task Manager flickers too, focus on the display driver.
  4. If Task Manager stays stable while the rest flickers, focus on recently changed apps.
2

Roll back or update the display driver when the driver branch fits

Medium risk

Why this belongs here: A recent display-driver change can be reversed without reinstalling unrelated Windows components.

  1. Open Device Manager > Display adapters.
  2. Open the graphics device Properties > Driver.
  3. If the issue began after a driver update and Roll Back Driver is available, use it.
  4. Otherwise check Windows Update and the PC/GPU manufacturer for the appropriate current driver.
3

Update or remove the incompatible app when Task Manager stays stable

Medium risk

Why this belongs here: A non-flickering Task Manager points away from the core display driver in Microsoft’s diagnostic split.

  1. Identify apps installed or updated just before the flicker began.
  2. Update the suspected app first.
  3. If the problem persists, uninstall that app and test again.
Stop condition

When this guide stops being the right path

If the display is blank rather than flickering, or the PC shows a stop-code screen, use the blank-screen or stop-code path instead.

If the problem is still not fixed

If flickering persists in Safe Mode or appears before Windows loads, investigate hardware, cable, panel or firmware causes rather than continuing app-level changes.
