Desktop icons disappear in lower half of screen

For the past few days, my desktop icons in the lower left-hand side of my screen become invisible. If I slowly move my cursor over the right spot, the little menu pops up telling me what icon I am over, and I can either drag it to the upper left half of the screen where it becomes visible, or double click the invisible icon to open the program. I have attached screen shots using the Recycle Bin as example. First one shows Bin. Second one show partial disappearance of Bin as I drag it below the "event horizon." Third show it completely disappears as I drag further down. Fourth shows pop-up as my cursor hovers over the spot where it exists but is invisible. Fifth shows Bin after dragging it back up. If I drag any icons to the middle or right side of the screen (either upper or lower half), the same bizarre behavior happens...they disappear. I have turned off Tablet mode which did not help. I have rebuilt Icon Cache which brings all icons back, but so does just a simple Restart. But they just disappear again. I think they may disappear after I play Uru Complete Chronicles, but need to test that some more. Anybody know a cure for this weird problem?
Many thanks.

What do you use to get this group of icons at the top of the screen?



Maybe it is interfering with displaying the desktop icons? Tried turning it off?

Thank you, I had checked the Desktop Icons option one without any success. Also, the icon bar at the very top of the screen is from Dell, called Dell Dock. It has never caused a problem in Windows 7 and has not caused a problem with Windows 10 since I first upgraded to 10 in March 2016. I have recently run DISM/Cleanup Image and SFC. I have not had the problem since then, but it has only been 24 hours. I will give it a few more days before marking this as "resolved."
