C++ Builder 10.1 with update 2 on Windows 10

I bought a LG 27UD69P monitor. I have 3 monitors on my desk. I have the 27 LG, and 2 Dell 27" with 2560x1440 resolution. The LG's resolution is 3840x2160.

I have my Structure Panel on the LG monitor. I try to drag and move the Structure Panel to a new location. When I first press and hold down the mouse button and move it just slightly (a few pixels) a blue rectangle appears to show you where the Structure Panel's new location. The problem is the size of the rectangle is much smaller than the Structure Panel, and it's location is several inches to the left of where the mouse cursor is.

Here is a picture www.douglashay.com/tracks/lg.png

In the picture I started a drag drop on the Structure Panel, and I moved the mouse about 1 inch (green line). Note how the blue rectangle is smaller than the the Structure Panel, and it's about 4 inches to the left of where it should be.

If I drag and move on the Dell monitors it works normally, only the LG monitor has this issue.

Yes, I have also the same problem if monitors have different resolution.
