Bug Report: Intel Iris Xe Graphics – Driver 32.0.101.7076 – Random Blackouts & IGCL ctlInit Exception

System Information

• Laptop Model: Dell Inspiron 15 3511

• GPU: Intel Iris Xe Graphics (integrated)

• OS: Windows 11 Core Single Language, Version 23H2 (Build 26100.6584)

• Driver Version: 32.0.101.7076 (latest from Intel site)

Issue Description
After updating to Intel Graphics driver 32.0.101.7076, my laptop randomly experiences screen blackouts even when idle on the desktop (not only during video playback).

Event Viewer consistently logs the following error at the time of the blackout:
Log Name: Intel Graphics Software
Source: Intel.GraphicsSoftware.Service
Event ID: 134
Level: Error
Message: {"category":"Igcl","level":"Error","message":"3rd Party - IGCL ctlInit - Exception"}

This suggests a failure in IGCL (Intel GPU Control Library) initialization.

Steps Already Taken

• Confirmed issue happens while idle and on desktop, not only during apps.

• Ran sfc /scannow → repaired unrelated Bluetooth driver corruption (not graphics).

• Confirmed blackouts started only after upgrading to driver 32.0.101.7076.

Expected Behavior

• Stable display without random blackouts.

• Intel Graphics Software Service should not throw recurring IGCL ctlInit exceptions.

Hi @anonymus-1 ,

The generic Intel driver provides users with the latest and greatest feature enhancements and bug fixes that computer manufacturers (OEMs) might not have customized yet. OEM drivers are handpicked and include customized features and solutions to platform-specific needs. Installing this Intel generic graphics driver will overwrite your handpicked OEM graphics driver. Users can check for matching OEM driver versions at OEM websites. For more information on how the installation of this driver may impact your OEM customizations, see this article.

Since the issue started after the update, it's possible that the system is only compatible with the driver provided by Dell. Try rolling back the current driver and installing the one recommended by your laptop manufacturer.

Best regards,

Randy T.
