Windows 10: Start menu lag caused by switching the GPU

Hello
I installed a fresh copy of Windows 10 v1903 on my ASUS N53SV laptop. I updated drivers using windows update.
I noticed that every time I try to open the start menu, It shows after a small (say half a second) lag. If I keep pressing start key, the subsequent openings are lag free. But if I wait for a few seconds and try to open start menu, the lag happens again.
I also noticed the lag is concurrent with color change of GPU indicator light. Every time the lag occurs, current GPU changes from Intel HD to dedicated Nvidia GeForce for a brief time.
I tried to track GPU switching using Nvidia GPU Activity app, but it doesn't show any app using dedicated GPU (maybe because it switches back to Integrated GPU shortly)

I tried the following too:
- in nvidia control panel, changed the default graphics processor to Integrated.
- added explicit rules to use integrated graphics for searchui.exe, dwm.exe and startmenuexperiencehost.exe

The only solution which is not optimal is to make nvidia the default GPU.

Can you help me track the culprit?

:)

 

Feature suggestion: Add right-click menu

Suggestion: Please add a Windows 7 Jump-List and/or right-click menu to the GPU-Z icon in the Windows taskbar. Possible menus in it would be "Exit" and "About GPU-Z...".
Maybe also "Switch to tab 1/Switch to tab 2/Switch to videocard 1/Switch to videocard 2" too.
Examples of programs that have such menus are ICQ, Skype, AIM.

NOTE: It seems for a right-click menu, Windows 7 is not needed - it works on WinXP and Vista too.
But even a Windows 7 Jump-list may be good enough.
What do you think?
