Thank you very much for sharing your issue with the Intel Communities Team, riom123. I will be more than glad to assist you.
After a clean installation of Windows 10* on this specific processor with Radeon* graphics first, you need to install the Intel® HD Graphics 630 drivers and then the Radeon™ RX Vega M GL drivers. If you did not follow that order after the installation of the Operating System, please uninstall both drivers and install them in that order.
In addition, I would appreciate if you can share with us a video when the issue occurs. Furthermore, is this happening with a game, application or just by the normal use of the computer? Finally, please share with us the results of the DxDiag* report, in order to generate it, please follow these steps:
1. In the keyboard, press WinLogo key + R.
2. In the Run box please type dxdiag and hit Enter.
3. Click on Save All Information (save it in your desktop).
4. Attach the .txt file that was generated. To attach a file, you must click the “Attach” option on the bottom right-hand corner of the response box.
Thank you for your suggestion regarding the driver order specification. I have uninstalled both AMD and Intel drivers and reinstalled them in the order you suggested, and still seem to have the micro-lag issue.
The issue seems to occur just by normal use of the computer, and I assume that this is something to do with the switchable graphics.
Another issue I have encountered is with the UAC prompt. (Again, these issues only occur when the AMD display driver is enabled)
I get a rather long pause, waiting for the UAC prompt, and hear the Windows UAC chime before eventually the dialog box displays.
I'm not sure how I would capture the lag as it seems to be an intermittent problem, however I will try and share a video of the problem.
As requested, I have attached the logs from the dxdiag report.

I would like to step in and help if that is ok with you.
I was reading the issue description you provided, and it looks to be the same issue that is described here: dGPU Switch and Freeze Problem. Please check it out and let me know if that is not the case.
It is a long thread, but in summary it talks about slow performance on different aspects of the User Interface (UI) occurring exclusively on laptops with Hybrid Graphics (i.e. Intel Graphics + Discrete graphics cards).
Intel was able to reproduce the issue, and after exhaustive research and debugging, we were able to provide a fix that is included in any driver released after build number 4982 (6th Generation and newer). After implementing the code change, we noticed there were some remaining stuttering happening in various areas of the OS experience. We've now concluded that any remaining stuttering is coming from a different component (OS and Discrete graphics driver). This concluded Intel's investigation, and we are now considering this issue closed from the Intel driver side, though Intel will remain in communication with the other parties (OS and Discrete graphics card vendor) to assist in any way we can should they desire.
For now, please install all the latest updates for both Windows and the discrete graphics card as they become available.
