Windows 10: Windows 11 unusual behavior with multi monitors after update.

Hi, First, I apologize if this is the wrong place to ask this question, and I did some searching on the forum to see if anyone had posted similar issues and could not find any examples, hopefully someone can point me in the right direction. I have an alienware m15 r6 with a 3060 graphics card. I bought the laptop in november and it came with windows 10 on it. I held off on updating to windows 11 at first but decided to make the transition while updating my other systems.

Windows 10 KB3213986 Update Cripples Multi-monitor Gaming

The recent Cumulative Update for Windows 10 (KB3213986) cripples multi-monitor gaming, looking at the way Microsoft worded its "known issues" text. After the update is applied, users with multi-monitor setups could experience screen stuttering or clipped screens when running 3D apps on machines with more than one monitor. The only workaround Microsoft suggests for now entails running your 3D apps in non-fullscreen modes, such as windowed-maximized (pseudo-fullscreen) or windowed modes. Microsoft also goes as far as to suggest that people with multi-monitors could try starting their 3D apps with just one monitor connected.

"Users may experience delayed or clipped screens while running 3D rendering apps (such as games) on systems with more than one monitor," the change-log for the KB3213986 update reads. "To work around this issue please consider the following options: 1. Running the application in Windows mode (not full screen), or 2. Starting the application with only one monitor connected," it adds. The update effectively cripples multi-monitor gaming, using technologies such as AMD Eyefinity or NVIDIA 3D Vision Surround.

This should be enough to get the conspiracy theorists suggesting that Microsoft is intentionally crippling multi-monitor support in fullscreen mode since games sold on the Microsoft Store all work in the pseudo-fullscreen mode...

Or it could just be an idiotic bug that will be fixed in time.

 

Unusual hard disk behavior


I have power options set to never turn the hard disk off. So far the drive hasn't been shutting off, but the constant activity has continued.

This is my task manager processes sorted by most disk activity:





I also ran the Western Digital Diagnostics app and it passed the tests as you can see here:





As suggested I'm in the process of backing up my drive, but I would certainly prefer it not die on me. *Sad
