Desktop Window Manager High Memory

Anonymous

Desktop window manager is using between 1.5GB and 3GB or memory at any given time and then will crash and then reconnect to my monitors and docking station (really inconvenient during meetings). I'm running 2, 27" 4K monitors through a Dell WD19 Docking station and a built in 14" monitor.

My OS is Windows 11 Pro 23H2 build: 22631.3296

My display adapters are Intel Iris Xe Graphics and an NVIDIA RTX A5500 Laptop GPU.

I've already done all driver updates, OS updates, restarts, reboots, end task, display configurations, and malware scans.

I'd love help on decreasing the memory usage so it will work as advertised and stop crashing.

    1GB isn't much except it's using that for nothing and as I open more windows it increases rapidly. It continues to increase memory usage until it hits about 3.5GB and that's when it typically crashes. Sadly, it's not a bluescreen when it crashes. The computer screen will go black and disconnect from all monitors and audio devices and then reconnect. Which is irritating but not a deal breaker until it does it while I'm presenting on a meeting. Then it reconnects to everything. When it does, the DWM.exe is started again and starts at 1GB of memory and then starts the climb to 3.5GB again before resetting everything. It's acting like a memory leak but I'm not sure how I would be able to prove that.

    I have the 3672 version, and my dwm.exe can use up to 38GB (committed)
    I think there's a memory leak somewhere, and this is probably a different issue than this post is about.

    Still, this is really an issue that should be fixed.

    I gave it a go with the updates. It's still hovering at 1.6gb and spiking later. I'm guessing this is just going to be my reality going forward.

    Your intel processor supports the following

    Max Resolution (HDMI)‡ 4096 x 2304 @ 60Hz

    Max Resolution (DP)‡ 7680 x 4320 @ 60Hz

    Max Resolution (eDP - Integrated Flat Panel)‡ 4096 x 2304 @ 120Hz

    Max Resolution (HDMI) and (DP) is the maximum resolution supported by the processor via the HDMI and DP interface (24 bits per pixel & 60Hz).

    System or device display resolution is dependent on multiple system design factors; actual resolution may be lower on your system.

    Intel® Core™ i9-12900H Processor

    You can try the latest Generic graphics driver from the Intel site

    Intel® Graphics Driver 31.0.101.5333 (WHQL Certified)

    Intel® Arc™ & Iris® Xe Graphics - Windows*

    Generic drivers do not have custom features, sometimes it gives better performance in fewer system configurations.

    I am using same driver Intel® Graphics Driver 31.0.101.5333 (WHQL Certified) for Intel i5-13500.

    Use DDU software to completely uninstall existing software in Windows safe mode.

    If you have the option to select the default graphics card from bios, select Nvidia, use the Nvidia generic driver from the Nvidia site

    NVIDIA RTX Enterprise Production Branch Driver R550 U4 (551.86)

    https://www.nvidia.com/Download/driverResults.aspx/223432/en-us/

    NVIDIA RTX Enterprise New Feature Branch Driver R545 U2 (546.01)

    Thank you for the steps.

    I disabled the fast startup and did the clean boot and it's still taking 1GB of memory on a fresh start with nothing but this web browser window open.

    What would be the next step?

    Thanks!
