Step-by-step fix guide for Windows 10 and Windows 11.
Right-click the Malwarebytes shortcut → Properties → Shortcut tab → in Target field, add --disable-gpu at the end. Example: "C:\Program Files\Malwarebytes\Anti-Malware\mbam.exe" --disable-gpu. Click OK and relaunch.
Right-click the Malwarebytes shortcut → Properties → Compatibility tab → check "Override high DPI scaling behavior" → set to "Application". Click OK and relaunch.
Open Device Manager (Win+X → Device Manager), expand Display adapters, right-click your GPU and select Update driver. Outdated display drivers are a common cause of blank rendering.
Open Run (Win+R), type %LocalAppData%\Malwarebytes and press Enter. Delete the "Cache" folder. Relaunch Malwarebytes — it will rebuild the cache.
If above steps fail, use the Malwarebytes Support Tool to clean uninstall, then download and reinstall a fresh copy from malwarebytes.com.
A blank white or grey Malwarebytes window is caused by a GPU rendering failure in the Electron-based interface. This usually happens after a Windows update changes display scaling settings or after a GPU driver update.
No. The --disable-gpu flag only affects how the Malwarebytes user interface renders. All protection features — real-time scanning, threat detection, ransomware blocking — continue to work normally.
Windows updates sometimes reset DPI scaling settings. After a Windows update, try the DPI fix in Step 2 first — this resolves the blank screen in most post-update cases.
