It had the same problem once a few days ago but I am trying other things as far as tests are concerned because there are several well known issue(s) that are not new that people have experienced for years so I will report back when I will since you did say the thread will remain open as long as I need it.
1) Issue #1 is quoted as follows which is experienced by others:
“9955 has the same issues as 9922 and 9894, at least for me, with the playing video in the browser (Edge Chromium) simply locks up the image, remains static yet the cursor still works.”
with the response provided by others:
"Try disabling MPOs if that helps for your issue with these reg files: nvidia.custhelp.com/app/answers/detail/a_id/5157
I found out long time ago, that Intel drivers are buggy with MPOs on (default), and it it worse under windows 11. Reported it here bugs.chromium.org/p/chromium/issues/detail?id=1258325
I also have the issue on older Intel gen GPU, HD5300, that Chrome / Edge randomly freezes for 30 seconds or so then unstucks. Intel GPU drivers are just a mess since years. Intel driver devs dont know what theyre doing. The 1 year old bug with DWM memory leak is still not fixed, there is hope they they FINALLY maybe found whats causing it."
This is what I am currently testing with the MPOs (Multiplane) disabled to see if the problem still exists or not.
2) Issue #2 has a long thread that started in October 23, 2020 which is still active:
https://community.intel.com/t5/Graphics/BUG-dwm-exe-uses-memory-leakage-with-Intel-HD-Graphics-630/td-p/1222297
This one others can test as the thread is long enough already and it even has Intel Moderators who acknowledge the issue while Intel Driver Developers have not been able to duplicate the issue. 9922 according to the moderators) of that thread is also the first version which supposedly fixes issue #2 so it may have created new issue(s) as I am on a clean install of 9976 after all even though I have installed 9955, 9976 would immediately install via Windows Update on it’s own even after I disabled driver updates via Windows Updates so there really isn’t a choice. Even if I got the Dell 27.x.x.x driver, Windows Update will still install 9976 immediately over it on it’s own.
Speaking about the Dell driver, the whole reason for that release is not because of Windows 11 but rather:
"This package contains the Intel Security Advisories INTEL-SA-00508 and INTEL-SA-00566-1. A security advisory is a statement when a security vulnerability impacts a product, and a remedy is available for the vulnerability.
Fixes & Enhancements
- Driver updates to address the Intel Security Advisories INTEL-SA-00508 and INTEL-SA-00566-1.
"
which came from here:
and as seen on:
https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=43crj&oscode=wt64a&productcode=xps-15-9570-laptop
It states that this is a 32bit driver and not 64bit which obviously can’t be true as 64 bit OSes need 64 bit drivers so these are really security patched Windows 10 drivers and not really Windows 11 certified drivers as Windows 11 can use Windows 10 drivers if there are no real Windows 11 drivers.
So I will test issue #2 after I see the results from issue #1. It is hard to give a estimated timeframe because when I say 7 days, I am talking about 7 days uptime from the time of the reboot since as you are aware, Windows has User and GDI Resource limits so a lot of times even with 32GB of memory, a reboot is needed because either the CPU is pushing 99% or even if it wasn’t, the system is nearly non-responsive because of the resources running out. And there might be other reasons why I need to reboot so it might be easier if I just post peridically instead of 7 calendar days from the time of my post. And just for reference, I did just reboot 2 hours earlier because of the sluggish issue even when the CPU went back to 50%, there were serious lags as even killing Google Chrome and starting it again, a mouse click would take close to 5 minutes to respond.
And in the referenced thread, it also mentions:

“Build date of 30.0.101.1002 is October 13, 2021, Gabriela said Intel just started to look into a real fix at October 21, 2021”
Gabriela who is the Intel moderator for that thread.
Just for the record, I did a clean install of 30.0.101.1002 turning the internet off but as soon as I reconnect to the internet, Windows Update downloads and install 30.0.100.9976 so I rebooted as prompted and installed 30.0.101.1002 using the .exe installer and prior to rebooting, I ran DriverStoreExplorer and removed the remains of 30.0.100.9955 which the previous 30.0.100.9976 installed over via Windows Update and also 30.0.100.9976 so the latest 7 day countdown begins at:
