Just an update from our side. For our 2 Dell Latitude 7350 devices (with Intel Core Ultra CPUs) the issue is still "resolved" as well.
But also by using an Intel driver version from before this issue has been first reported.
In our case the Intel Graphics driver 32.0.101.6078 works without issues (as described in our last post on page 3 back in February).
The annoying thing is that this driver version is not available on Intel's download page anymore. (Although we do have an internal backup just in case.)
We did not try any newer Intel driver versions since then as we have not seen any changelog entry that would suggest a fix to this issue. Interestingly though, the issue is also not listed under known issues...
Anyway, if anyone currently still has the issue with green artifacts, Dell provides a download to this driver version which you can try as well if you want:

Use "Extract" on the Dell setup to get the Intel installer. (Although the Dell setup seems to just run the Intel installer anyway.)
As for the installation process, it should be sufficient to:
- Uninstall "Intel(R) Graphics Software & Drivers" from the "Apps" list, followed by a device restart. (Remove all listed components which should be default.)
- Start the (extracted) Intel installer via "Installer.exe".
- Check the "Execute a clean installation" option before confirming the installation.
Note: As already mentioned by @apokaluptikos 2 posts above, DDU (Display Driver Uninstaller) can help removing any remaining Intel drivers. Alternatively uninstall any remnants via device manager. For this workaround it is essential that no newer Intel Graphics driver versions are being used. In our case, it was not necessary as the Intel installer removed all driver versions without issues.
What to be aware of:
We are using software deployment for Windows and driver updates, meaning automatic Windows Updates are disabled. So we do not have any issues with the old Intel driver getting overwritten by a newer version. If you have to rely on automatic Windows Updates then the issue might reappear quite fast in case that a newer Intel Graphics driver version than 32.0.101.6078 is already getting deployed by it automatically.
And of course: No guarantee that this will resolve the issue. We can only say that it resolved the issue on our 2 Dell Latitude 7350 devices.
