latest gfx drivers cause problems in windows 11.

HI,

So the latest two gfx drivers from intel , being 5186 & 5194 both cause problems in windows 11.

They don't play nice on my system in combination with a discrete AMD card and their 24.1.1 driver.

Symptoms are that the Intel Gfx drivers can't get the screen to run anymore,

The intel gfx connected screen either flickers on/off or stays off all together.

So i reverted to intel 101.1994 driver since that is also the last ever Intel driver that can have the clockspeeds of the intel UHD 750 low under idle. Any driver later than 1994 keeps the IGPU clock pegged at maximum.  I reported this before but INTEL clearly does not give a **bleep**.

Drivers are getting worse and worse for the 11th gen IGPU's.

What is exact model of your processor and motherboard? You can also share the SSU logs of your computer so we can review it. Here's the link: https://www.intel.com/content/www/us/en/support/articles/000057926/memory-and-storage.html

Tried the latest 5330 driver and the results are the same as previous two drivers.

Cold booting leaves the iGPU connected screen black, after windows started it tries to get it working but it fails in the end.

reverting to a driver before any of the latest three and the problem is gone.

What have driver devs changed ?? They know what the problem is for sure.

Just like they must know why the idle clockspeed is now stuck at 1300MHz since after driver 1994...

Also seems windows now mistakes itself in what monito/gfx card should be primary and what should be secondary screen.

Amd adrenalin pannel opens on intel connected screen which is supposed to be secondary, intel arc control opens on my primary amd connected screen. Also main screen is 100% and secondary is 150% sized, but with these latest three drivers the screens size gets switched, So your driver does something very wrong.

All that changed in the latest three drivers, intel broke a perfect working system with their gfx drivers that don't play nice.

And i can also report that the screen connected to iGPU gets reported by ARC as being HDR capable/enabled when it is not a HDR screen AT ALL.

So why does windows 11 start mixing up screens ever since Intels latest three gfx drivers??

Seems like Intel team made a mistake again.

How about performing a ddu to remove the drivers and then install the latest driver? This is just a sussgestion to narrow down the issue. Here’s the link:

So i did use DDU , several times for each driver test, 

and i noticed that after installing, then uninstalling and DDU cleaning there was still some Intel Gfx driver being locked on the system.

I had to force delete those with RAPR tool. 

Then after cleaning, rebooted and tried the new 5330 again, and this time the install seems to have worked normal.

I can now restart and cold boot without the secondary screen remaining black. 

This was something very odd but i guess something must have been wrong with one of the latest drivers that did mess up something in windows 11.

Maybe this is related to the problem of getting IOMMU errors reported by windows 11 each time a new intel driver gets installed...
