I have a Dell Precision 5540 with Core I7-9850H 32GB Ram 512GB SSD NVIDIA Quadro T1000 4GB 15.6″ Inch FHD running Windows 10 22H2.
Recently, I have been noticing flashes in Windows Explorer and random restarts of the taskbar; all its icons disappear suddenly and load again.
As you can see in the videos, the Control Panel window flashes (Not Responding) momentarily upon simple scrolling up and down and sometime its icon in the taskbar replicates to another instance and the new instance disappears instantly.

Additional Observations:
1- I previously configure my touchpad’s three-finger gesture to be a middle click. It is functional anywhere; in Chrome to close tabs, or in Windows Explorer to open new windows if the taskbar icon is middle-clicked. But I am no longer able to close a Windows Explorer window by clicking its thumbnail preview as I used to do unless I click on an empty area on the taskbar beforehand. It seems like the preview doesn’t get the necessary focus to perform the action.

2- The battery icon and sometimes the sound icon disappear from the system tray.
What I Did:
1- Updated the two graphics drivers (intel and Nvidia) to the latest drivers published in their official websites, making sure all settings are reset during installation. Result: None.
2- Reverted to the driver versions published on Dell’s website for my laptop. Result: None.
3- Reset my bios to its default values. Result: None.
4- Set “Visual Effects” in System Properties Performance Option to “Adjust for best performance”. Result: None.
5- Disabled Hardware-accelerated GPU Scheduling. Result: None.
I cannot remember that I have done any recent changes in my system except for the usual updates of Chrome, Thunderbird, and Avast AV.
