dwm.exe ram usage in Windows 11 24H2

"Desktop windows manager" ram usage hovers around 350MB and touches 500 MB often. Is this normal behavior? I think I've noticed this after yesterdays update.

My PC is not running Windows 11 (running windows 10 and dwm.exe hovers around 90 MB), can you please confirm what are ram usage for this process is like in your windows 11 system.

WINDOWS 11

The more screens you connect, the more memory it uses.
The higher the resolution of those screen, the more memory it uses.
If you use big size/ high definition images as background that also increases it memory uses.

So if you have 3 screen with 4k resolution, with high definition images it could reach that amount.
If you use 1 screen on 1920x1080 then the 350to 500mb is to much.

Also some application uses hardware accelation, so that can impact also the memory usage. Like edge/chome.
If you exit/quit edge, does it still stays high?
if so, then kill dmw.exe , screen will flash a time, and dmw.exe will start automaticly. Does memory usage is low now? Start edge, is memory usage growing then?

Also try updating you intel graphic card drivers, as they also could be leaking.

@Fabler2 Please tell about the build number of Windows 11 you are running.

Not using any external monitor and inbuilt screen is 2k 120 hz panel. After closing all apps and killing dwm.exe, it starts at 177 MB and jump right back to ~350 MB, with peaks of 500 MB.
Tired clean install Intel GPU driver, no changes.

Most likely this behavior started after KB5051987 and KB5052978 update, or else I would have noticed.
Would be great if someone who is on Build 26100.3194, can confirm.
